Singular they
Singular they is the use in English of the pronoun they or its inflected or derivative forms, them, their, theirs, and themselves singular pronoun. It typically occurs with an unspecified antecedent, as in sentences such as:
- "Somebody left their umbrella in the office. Could you please let them know where they can get it?"
- "The patient should be told at the outset how much they will be required to pay."
- "But a journalist should not be forced to reveal their sources."
In the early 21st century, use of singular they with known individuals emerged for people who do not identify as male or female, as in the following example:
- "This is my friend, Jay. I met them at work. They are a talented artist."
Inflected forms and derivative pronouns
The "singular they" permits a singular antecedent, but is used with the same verb forms as plural they, and has the same inflected forms as plural they, except that in the reflexive form, themself is sometimes used instead of themselves.Pronoun | Subjective | Objective | Prenominal possessive | Predicative possessive | Reflexive |
He | is my son. | When my son cries, I hug. | My son tells me age. | If I lose my phone, my son lends me. | My son dresses. |
She | is my daughter. | When my daughter cries, I hug. | My daughter tells me age. | If I lose my phone, my daughter lends me. | My daughter dresses. |
Plural they | are my children. | When my children cry, I hug. | My children tell me ages. | If I lose my phone, my children lend me. | My children dress. |
are my child. | When my child cries, I hug. | My child tells me age. | If I lose my phone, my child lends me. | My child dresses . | |
Generic he | is my child. | When my child cries, I hug. | My child tells me age. | If I lose my phone, my child lends me. | My child dresses. |
Themself is attested from the 14th to 16th centuries. Its use has been increasing since the 1970s or 1980s, though it is sometimes still classified as "a minority form". In 2002, Payne and Huddleston, in The Cambridge Grammar of the English Language, called its use in standard dialect "rare and acceptable only to a minority of speakers" but "likely to increase with the growing acceptance of they as a singular pronoun". It is useful when referring to a single person of indeterminate gender, where the plural form themselves might seem incongruous, as in:
- "It is not an actor pretending to be Reagan or Thatcher, it is, in grotesque form, the person themself." — Ian Hislop ; quoted in Fowler's
Regional preferences
- "Where a recipient of an allowance under section 4 absents themself from Canada ..." — War Veterans Allowance Act, section 14.
- "... the following conditions are imposed on a person or group of persons in respect of whom a deposit is required:... to present themself or themselves at the time and place that an officer or the Immigration Division requires them to appear to comply with any obligation imposed on them under the Act." — Immigration and Refugee Protection Regulations, section 48.
Usage
Informal spoken English exhibits nearly universal use of the singular they. An examination by Jürgen Gerner of the British National Corpus published in 1998 found that British speakers, regardless of social status, age, sex, or region, used the singular they overwhelmingly more often than the gender-neutral he or other options.
Older usage
Singular they is found in the writings of many respected authors. Here are some examples, arranged chronologically:- "Eche on in þer craft ys wijs." — Wycliffe's Bible, Ecclus. 38.35
- "And whoso fyndeth hym out of swich blame, They wol come up..." — Chaucer, "The Pardoner's Prologue" of The Canterbury Tales quoted by Jespersen and thence in Merriam-Webster's Concise Dictionary of English Usage.
- "Eche of theym sholde ... make theymselfe redy." — Caxton, Sonnes of Aymon
- "If a person is born of a ... gloomy temper ... they cannot help it." — Chesterfield, Letter to his son ; quoted in Fowler's.
- "A person can't help their birth." — Rosalind, in W. M. Thackeray, Vanity Fair ; quoted from the OED by Curzan in Gender Shifts in the History of English.
- "Now nobody does anything well that they cannot help doing" — Ruskin, The Crown of Wild Olive ; quoted in Fowler's.
- "Nobody in their senses would give sixpence on the strength of a promissory note of the kind." — Bagehot, The Liberal Magazine ; quoted in Fowler's.
Prescription of generic ''he''
- "If any one did not know it, it was his own fault." — George Washington Cable, Old Creole Days ; quoted by Baskervill.
- "Every person who turns this page has his own little diary." — W. M. Thackeray, On Lett's Diary ; quoted in Baskervill, An English Grammar.
- "Suppose the life and fortune of every one of us would depend on his winning or losing a game of chess." — Thomas Huxley, A Liberal Education ; quoted by Baskervill.
- "No one shall be arbitrarily deprived of his nationality nor denied the right to change his nationality." — Article 15, Universal Declaration of Human Rights.
The earliest known explicit recommendation by a grammarian to use the generic he rather than they in formal English is Ann Fisher's mid-18th century A New Grammar assertion that "The Masculine Person answers to the general Name, which comprehends both Male and Female; as, any Person who knows what he says."
Nineteenth-century grammarians insisted on he as a gender-neutral pronoun on the grounds of number agreement, while rejecting "he or she" as clumsy, and this was widely adopted: e.g. in 1850, the British Parliament passed an act which provided that, when used in acts of Parliament "words importing the masculine gender shall be deemed and taken to include females". Baskervill and Sewell mention the common use of the singular they in their An English Grammar for the Use of High School, Academy and College Class of 1895, but prefer the generic he on the basis of number agreement:
Baskervill gives a number of examples of recognized authors using the singular they, including:
- "Every one must judge according to their own feelings." — Lord Byron, Werner, quoted as "Every one must judge of their own feelings."
- "Had the Doctor been contented to take my dining tables as any body in their senses would have done ..." — Jane Austen, Mansfield Park ;
- "If the part deserve any comment, every considering Christian will make it to themselves as they go ..." — Daniel Defoe, The Family Instructor ;
- "Every person's happiness depends in part upon the respect they meet in the world ..." — William Paley
- "... let us keepe a naturall order, and set the man before the woman for manners sake". — Wilson, The arte of Rhetorique ;
- "... the worthier is preferred and set before. As a man is set before a woman ..." — Wilson, The arte of Rhetorique ;
- "The Masculine gender is more worthy than the Feminine." — Poole The English Accidence ; cited by Bodine
- indeterminate persons of both sexes:
- *"the ideal that every boy and girl should be so equipped that he shall not be handicapped in his struggle for social progress ..." — C. C. Fries, American English Grammar,.
- known persons of both sexes:
- *"She and Louis had a game – who could find the ugliest photograph of himself." — Joseph P. Lash, Eleanor and Franklin
Contemporary use of ''he'' to refer to a generic or indefinite antecedent
- "The patient should be informed of his therapeutic options." — a text about prostate cancer
- "It wouldn't be as if the lone astronaut would be completely by himself."
- "Kitchen table issues ... are ones the next president can actually do something about if he actually cares about it. More likely if she cares about it!" — Hillary Rodham Clinton
- an indeterminate person of either sex:
- *"Now, a writer is entitled to have a Roget on his desk." — Barzun ; quoted in Merriam-Webster's Concise Dictionary of English Usage
- *"A Member of Parliament should always live in his constituency."
In 2015, Fowler's Dictionary of Modern English Usage calls this "the now outmoded use of he to mean 'anyone, stating:
In 2016, Garner's Modern English calls the generic use of masculine pronouns "the traditional view, now widely assailed as sexist".
Gender-neutral language
The earliest known attempt to create gender-neutral pronouns dates back to 1792, when Scottish economist James Anderson advocated for an indeterminate pronoun "ou".In 1808, poet Samuel Taylor Coleridge suggested "it" and "which" as neutral pronouns for the word "Person":
In the second half of the 20th century, people expressed more widespread concern at the use of sexist and male-oriented language. This included criticism of the use of man as a generic term to include men and women and of the use of he to refer to any human, regardless of sex.
It was argued that he could not sensibly be used as a generic pronoun understood to include men and women. William Safire in his On Language column in The New York Times approved of the use of generic he, mentioning the mnemonic phrase "the male embraces the female". C. Badendyck from Brooklyn wrote to the New York Times in a reply:
By 1980, the movement toward gender-neutral language had gained wide support, and many organizations, including most publishers, had issued guidelines on the use of gender-neutral language, but stopped short of recommending they to be third-person singular with a non-indeterminate, singular antecedent.
Contemporary usage
The use of masculine generic nouns and pronouns in written and spoken language has decreased since the 1970s.In a corpus of spontaneous speech collected in Australia in the 1990s, singular they had become the most frequently used generic pronoun. Similarly, a study from 2002 looking at a corpus of American and British newspapers showed a preference for they to be used as a singular epicene pronoun.
The increased use of singular they may owe in part to an increasing desire for gender-neutral language. A solution in formal writing has often been to write "he or she", or something similar, but this is often considered awkward or overly politically correct, particularly when used excessively. In 2016, the journal American Speech published a study by Darren K. LaScotte investigating the pronouns used by native English speakers in informal written responses to questions concerning a subject of unspecified gender, finding that 68% of study participants chose singular they to refer to such an antecedent. Some participants noted that they found constructions such as "he or she" inadequate as they do not include people who do not identify as either male or female.
They in this context was named Word of the Year for 2019 by Merriam-Webster and for 2015 by the American Dialect Society. On January 4, 2020, the American Dialect Society announced they had crowned they, again in this context, Word of the Decade for the 2010s.
Use with a pronoun antecedent
The singular antecedent can be a pronoun such as someone, anybody, or everybody, or an interrogative pronoun such as who:- with somebody or someone:
- *"I feel that if someone is not doing their job it should be called to their attention." — an American newspaper ; quoted by Fowler.
- with anybody or anyone:
- *"If anyone tells you that America's best days are behind her, then theyre looking the wrong way." President George Bush, 1991 State of the Union Address; quoted by Garner
- *"Anyone can set themselves up as an acupuncturist." — Sarah Lonsdale "Sharp Practice Pricks Reputation of Acupuncture". Observer 15 December 1991, as cited by Garner
- *"If anybody calls, take their name and ask them to call again later." Example given by Swan
- with nobody or no one:
- *"No one put their hand up." Example given by Huddleston et al.
- *"No one felt they had been misled." Example given by Huddleston et al.
- even where the gender is known or assumed:
- *"Under new rules to be announced tomorrow, it will be illegal for anyone to donate an organ to their wife." Ballantyne, "Transplant Jury to Vet Live Donors", Sunday Times 25 3. 1990, as cited by Garner
- with an interrogative pronoun as antecedent:
- *"Who thinks they can solve the problem?". Example given by Huddleston et al.; The Cambridge Grammar of the English language.
- with everybody, everyone, etc.:
- *"Everyone promised to behave themselves." Example given by Huddleston et al.
Notional plurality or pairwise relationships
- "Everyone loves their mother."
- I never did get into that football thing', she said after everyone returned to their seat."
- "Everyone doubts themselves/themself at one time or another."
- "At first everyone in the room was singing; then they began to laugh." Example given by Kolln.
- "Everybody was crouched behind the furniture to surprise me, and they tried to. But I already knew they were there." Example given by Garner.
- "Nobody was late, were they?" Example given by Swan.
- "At first everyone in the room was singing; then he or she began to laugh." Example given by Kolln.
- "Everybody was crouched behind the furniture to surprise me, and he tried to. But I already knew he was there."
- "Nobody was late, was he?"
- "Everybody was crouched behind the furniture to surprise me, but they instead surprised themself."
Use with a generic noun as antecedent
- with a noun used generically
- *"... if the child possesses the nationality or citizenship of another country, they may lose this when they get a British passport." From a British passport application form; quoted by Swan.
- *"cognitive dissonance: "a concept in psychology describes the condition in which a person's attitudes conflict with their behaviour". — Macmillan Dictionary of Business and Management, as cited by Garner.
- *"A starting point would be to give more support to the company secretary. They are, or should be, privy to the confidential deliberations and secrets of the board and the company. — Ronald Severn. "Protecting the Secretary Bird". Financial Times, 6 January 1992; quoted by Garner.
- with representatives of a class previously referred to in the singular
- *"I had to decide: Is this person being irrational or is he right? Of course, they were often right." — Robert Burchfield in U.S. News & World Report 11 August 1986, as cited in Merriam-Webster's Concise Dictionary of English Usage
- Even when referring to a class of persons of known sex, they is sometimes used.
- *"The sizing technology works via an iPhone app. To use it, a woman must take two pictures of themselves while wearing a tight fitted top in front of a mirror." Shane Hickey, "The innovators: the app promising the perfect-fitting bra", The Guardian 10 January 2015, as cited by Mark Liberman on "Language Log"
- *"I swear more when I'm talking to a boy, because I'm not afraid of shocking them". From an interview.
- *"No mother should be forced to testify against their child".
- They may also be used with antecedents of mixed genders:
- *"Let me know if your father or your mother changes their mind." Example given by Huddleston et al.
- *"Either the husband or the wife has perjured themself." Here themself might be acceptable to some, themselves seems less acceptable, and himself is unacceptable. Example given by Huddleston et al.
- Even for a definite known person of known sex, they may be used in order to ignore or conceal the sex.
- *"I had a friend in Paris, and they had to go to hospital for a month."
- The word themself is also sometimes used when the antecedent is known or believed to be a single person:
- *"Someone has apparently locked themself'' in the office."
Use for specific, known people, including non-binary people
A known individual may also be referred to as they if the individual is non-binary or genderqueer, regards male or female pronouns as inappropriate, and prefers they instead. Several social media applications permit account holders to choose to identify their gender using one of a variety of non-binary or genderqueer options, such as gender fluid, agender, or bigender, and to designate a pronoun, including they/them, which they wish to be used when referring to them. Though "singular they" has long been used with antecedents such as everybody or generic persons of unknown gender, this use, which may be chosen by an individual, is recent.
The singular they in the meaning "gender-neutral singular pronoun for a known person, as a non-binary identifier" was chosen by the American Dialect Society as their "Word of the Year" for 2015. In 2016, the American Dialect Society wrote:
The vote followed the previous year's approval of this use by The Washington Post style guide, when Bill Walsh, the Posts copy editor, said that the singular they is "the only sensible solution to English's lack of a gender-neutral third-person singular personal pronoun".
In 2019, the non-binary they was added to Merriam-Webster's dictionary.
The first non-binary main character on North American television appeared on the Showtime drama series Billions in 2017, with Asia Kate Dillon playing Taylor Mason. Both actor and character use singular they.
Acceptability and prescriptive guidance
Though both generic he and generic they have long histories of use, and both are still used, both are also systematically avoided by particular groups.Style guides that avoid expressing a preference for either approach sometimes recommend recasting a problem sentence, for instance replacing generic expressions with plurals to avoid the criticisms of either party.
The use of singular they may be more accepted in British English than in American English, or vice versa.
Usage guidance in American style guides
''Garner's Modern American Usage''
Garner's Modern American Usage recommends cautious use of singular they, and avoidance where possible because its use is stigmatized.- "Where noun–pronoun disagreement can be avoided, avoid it. Where it can't be avoided, resort to it cautiously because some people will doubt your literacy ..."
- "Speakers of resist this development more than speakers of, in which the indeterminate they is already more or less standard."
- "That it sets many literate Americans' teeth on edge is an unfortunate obstacle to what promises to be the ultimate solution to the problem."
- "Disturbing though these developments may be to purists, they're irreversible. And nothing that a grammarian says will change them."
''The Chicago Manual of Style'' (1993–2010)
From the 15th edition, this was changed. In Chapter 5 of the 16th edition, now written by Bryan A. Garner, the recommendations are:
and:
The American Heritage Book of English Usage (1996)
According to The American Heritage Book of English Usage and its usage panel of selected writers, journalism professors, linguists, and other experts, many Americans avoid use of they to refer to a singular antecedent out of respect for a "traditional" grammatical rule, despite use of singular they by modern writers of note and mainstream publications:''Publication Manual of the American Psychological Association''
The 6th edition of the American Psychological Association's Publication Manual rejects most use of singular they and gives the following example as "incorrect" usage:However, APA style endorses using "they" if it is someone's preferred pronoun.
The upcoming 7th edition of the APA Publication Manual, scheduled to be released in October 2019, will include guidelines on using singular they for bias free writing.
Strunk & White's ''The Elements of Style''
& E. B. White, the original authors of The Elements of Style, found use of they with a singular antecedent unacceptable and advised use of the singular pronoun. In the 3rd edition, the recommendation was still:The assessment, in 1979, was:
In the 4th edition, use of singular they was still proscribed against, but use of generic he was no longer recommended.
Joseph M. Williams's ''The Basics of Clarity and Grace'' (2009)
, who wrote a number of books on writing with "", discusses the advantages and disadvantages of various solutions when faced with the problem of referring to an antecedent such as someone, everyone, no one or a noun that does not indicate gender and suggests that this will continue to be a problem for some time. He "suspect that eventually we will accept the plural they as a correct singular" but states that currently "formal usage requires a singular pronoun".''The Little, Brown Handbook'' (1992)
According to The Little, Brown Handbook, most experts – and some teachers and employers – find use of singular they unacceptable:It recommends using he or she or avoiding the problem by rewriting the sentence to use a plural or omit the pronoun.
''Purdue Online Writing Lab''
The Purdue Online Writing Lab states that "grammar shifts and changes over time", that the use of singular they is acceptable, and that singular "they" as a replacement for "he" or "she" is more inclusive:''The Washington Post''
The Washington Post's stylebook, as of 2015, recommends trying to "write around the problem, perhaps by changing singulars to plurals, before using the singular they as a last resort" and specifically permits use of they for a "gender-nonconforming person".''Associated Press Stylebook''
The Associated Press Stylebook, as of 2017, recommends: "They/them/their is acceptable in limited cases as a singular and-or gender-neutral pronoun, when alternative wording is overly awkward or clumsy. However, rewording usually is possible and always is preferable."''The Handbook of Nonsexist Writing''
In The Handbook of Nonsexist Writing, Casey Miller and Kate Swift accept or recommend singular uses of they in cases where there is an element of semantic plurality expressed by a word such as "everyone" or where an indeterminate person is referred to, citing examples of such usage in formal speech. They also suggest rewriting sentences to use a plural they, eliminating pronouns, or recasting sentences to use "one" or "it".Usage guidance in British style guides
In the first edition of A Dictionary of Modern English Usage use of the generic he is recommended. It is stated that singular they is disapproved of by grammarians. Numerous examples of its use by eminent writers in the past are given, but it is stated that "few good modern writers would flout so conspicuously as Fielding and Thackeray", whose sentences are described as having an "old-fashioned sound".The second edition, Fowler's Modern English Usage continues to recommend use of the generic he; use of the singular they is called "the popular solution", which "sets the literary man's teeth on edge". It is stated that singular they is disapproved of by grammarians but common in colloquial speech. Numerous examples of its use by eminent writers are given, but it is stated that "few good modern writers would flout so conspicuously as Fielding and Thackeray".
According to the third edition, The New Fowler's Modern English Usage singular they has not only been widely used by good writers for centuries, but is now generally accepted, except by some conservative grammarians, including the Fowler of 1926, who, it is argued, ignored the evidence:
The Complete Plain Words was originally written in 1948 by Ernest Gowers, a civil servant, in an attempt by the British civil service to improve "official English". A second edition, edited by Sir Bruce Fraser, was published in 1973. It refers to they or them as the "equivalent of a singular pronoun of common sex" as "common in speech and not unknown in serious writing " but "stigmatized by grammarians as usage grammatically indefensible. The book's advice for "official writers" is to avoid its use and not to be tempted by its "greater convenience", though "necessity may eventually force it into the category of accepted idiom".
A new edition of Plain Words, revised and updated by Gowers's great granddaughter, Rebecca Gowers, was published in 2014.
It notes that singular they and them have become much more widespread since Gowers' original comments, but still finds it "safer" to treat a sentence like 'The reader may toss their book aside' as incorrect "in formal English", while rejecting even more strongly sentences like
- "There must be opportunity for the individual boy or girl to go as far as his keennness and ability will take him."
- "If someone loves animals, they should protect them."
- "If people love animals, they should protect them."
It expresses several preferences.
- "Generic/universal their provides a gender-free pronoun, avoiding the exclusive his and the clumsy his/her. It avoids gratuitous sexism and gives the statement broadest reference ... They, them, their are now freely used in agreement with singular indefinite pronouns and determiners, those with universal implications such as any, every, no, as well as each and some, whose reference is often more individual ..."
- "We can't afford to squander anyone's talents, whatever colour their skin is."
New Hart's Rules is aimed at those engaged in copy editing, and the emphasis is on the formal elements of presentation including punctuation and typeface, rather than on linguistic style, although – like The Chicago Manual of Style – it makes occasional forays into matters of usage. It advises against use of the purportedly gender-neutral he, and suggests cautious use of they where he or she presents problems.
The 2011 edition of the New International Version Bible uses singular they instead of the traditional he when translating pronouns that apply to both genders in the original Greek or Hebrew. This decision was based on research by a commission that studied modern English usage and determined that singular they was by far the most common way that English-language speakers and writers today refer back to singular antecedents such as whoever, anyone, somebody, a person, no one, and the like."
The British edition of The Handbook of Nonsexist Writing, modified in some respects from the original US edition to conform to differences in culture and vocabulary, preserved the same recommendations, allowing singular they with semantically plural terms like "everyone" and indeterminate ones like "person", but recommending a rewrite to avoid.
Australian usage guidance
The Australian Federation Press Style Guide for Use in Preparation of Book Manuscripts recommends "gender-neutral language should be used", stating that use of they and their as singular pronouns is acceptable.Usage guidance in English grammars
According to A Comprehensive Grammar of the English Language :The Cambridge Grammar of the English Language discusses the prescriptivist argument that they is a plural pronoun and that the use of they with a singular "antecedent" therefore violates the rule of agreement between antecedent and pronoun, but takes the view that they, though primarily plural, can also be singular in a secondary extended sense, comparable to the purportedly extended sense of he to include female gender.
Use of singular they is stated to be "particularly common", even "stylistically neutral" with antecedents such as everyone, someone, and no one, but more restricted when referring to common nouns as antecedents, as in
- "The patient should be told at the outset how much they will be required to pay."
- "A friend of mine has asked me to go over and help them ..."
There are also issues of grammatical acceptability when reflexive pronouns refer to singular noun phrases joined by or, the following all being problematic:
- "Either the husband or the wife has perjured himself."
- "Either the husband or the wife has perjured themselves."
- "Either the husband or the wife has perjured themself." .
The alternative he or she can be "far too cumbersome", as in:
- "Everyone agreed that he or she would bring his or her lunch with him or her.
- "Everyone's here, isn't he or she?
- "You should ask
Grammatical and logical analysis
Notional agreement
One explanation given for some uses of they referring to a singular antecedent is notional agreement, when the antecedent is seen as semantically plural:- Tis meet that some more audience than a mother, since nature makes them partial, should o'erhear the speech." — Shakespeare, Hamlet ; quoted in Merriam-Webster's Concise Dictionary of English Usage.
- "No man goes to battle to be killed." ... "But they do get killed. — George Bernard Shaw, quoted in Merriam-Webster's Concise Dictionary of English Usage
Distribution
Distributive constructions apply a single idea to multiple members of a group.They are typically marked in English by words like each, every and any. The simplest examples are applied to groups of two, and use words like either and or – "Would you like tea or coffee?". Since distributive constructions apply an idea relevant to each individual in the group, rather than to the group as a whole, they are most often conceived of as singular, and a singular pronoun is used:
- "England expects that every man will do his duty." — Nelson
- "Every dog hath his day." — John Ray, A Collection of English Proverbs, originally from Plutarch, Moralia, c. 95 AD, regarding the death of Euripides.
Referential and non-referential anaphors
The singular they, which uses the same verb form that plurals do, is typically used to refer to an indeterminate antecedent, for example:- "The person you mentioned, are they coming?"
- "Everyone returned to their seats."
The following shows different types of anaphoric reference, using various pronouns, including they:
- coreferential, with a definite antecedent :
- *"Your wife phoned but she didn't leave a message."
- coreferential with an indefinite antecedent:
- *"One of your girlfriends phoned, but she didn't leave a message."
- *"One of your boyfriends phoned, but he didn't leave a message.
- *"One of your friends phoned, but they didn't leave a message."
- reference to a hypothetical, indefinite entity
- *"If you had an unemployed daughter, what would you think if she wanted to accept work as a pole dancer?"
- *"If you had an unemployed child, what would you think if they wanted to accept work as a mercenary or a pole dancer?"
- a bound variable pronoun is anaphorically linked to a quantifier :
- *"No one put their hand up."
- *"Every car had its windscreen broken."
Cognitive efficiency
On the other hand, when the pronoun they was used to refer to known individuals, reading was slowed when compared with use of a gendered pronoun consistent with the "stereotypic gender".
The study concluded, that "the increased use of singular they is not problematic for the majority of readers".
Comparison with other pronouns
The singular and plural use of they can be compared with the pronoun you, which had been both a plural and polite singular, but by about 1700 replaced thou for singular referents. For "you", the singular reflexive pronoun is different from its plural reflexive pronoun ; with "they" one can hear either "" or "" for the singular reflexive pronoun.Singular "they" has also been compared to "royal we", when a single person uses first-person plural in place of first-person singular pronouns. Similar to singular "you", its singular reflexive pronoun is different from the plural reflexive pronoun.
While the pronoun it, which is used for inanimate objects, can be used for infants of unspecified gender, it tends to be dehumanizing, and is therefore more likely in a clinical context. In a more personal context, the use of it to refer to a person might indicate antipathy or other negative emotions.
It can also be used for non-human animals of unspecified sex, though they is common for pets and other domesticated animals of unspecified sex, especially when referred to by a proper name. Normally, vertebrate birds and mammals with a known sex are referred to by their respective male or female pronoun.
It is uncommon to use singular they instead of it for something other than a life form.
