The Old English term wyrd derives from a Common Germanic term *wurđíz. Wyrd has cognates in Old Saxonwurd, Old High Germanwurt, Old Norse urðr, Dutch worden, and German werden. The Proto-Indo-European root is *wert- "to turn, rotate", in Common Germanic *wirþ- with a meaning "to come to pass, to become, to be due".
Old English wyrd is a verbal noun formed from the verb :wikt:weorþan|weorþan, meaning "to come to pass, to become". The term developed into the modern English adjective :wikt:weird|weird. Adjectival use develops in the 15th century, in the sense "having the power to control fate", originally in the name of the Weird Sisters, i.e. the classical Fates, in the Elizabethan period detached from their classical background as fays, and most notably appearing as the Three Witches in Shakespeare's Macbeth. In many editions of the play, the editors include a footnote associating the "Weird Sisters" with Old English wyrd or "fate". From the 14th century, to weird was also used as a verb in Scots, in the sense of "to preordain by decree of fate". Of note is the use of "weird" in Frank Herbert's Dune to connote an ability to amplify or empower, e.g., certain words being used as "weirding words." The modern spelling weirdfirst appears in Scottish and Northern English dialects in the 16th century and is taken up in standard literary English from the 17th century. The regular modern English form would have been wird, from Early Modern Englishwerd. The replacement of werd by weird in the northern dialects is "difficult to account for". The most common modern meaning of weird - "odd, strange" - is first attested in 1815, originally with a connotation of the supernatural or portentous, but by the early 20th century increasingly applied to everyday situations.
Wyrd is a feminine noun, and its Norse cognate urðr, besides meaning "fate", is the name of one of the Norns; urðr is literally "that which has come to pass", verðandi is "what is in the process of happening" and skuld "debt, guilt". "Wyrd has been interpreted as a pre-Christian Germanic concept or goddess of fate by some scholars. Other scholars deny a pagan signification of wyrd in Old English literature, but assume that wyrd was a pagan deity in the pre-Christian period." Between themselves, the Norns weave fate or ørlǫg. According to Voluspa 20, the three Norns "set up the laws", "decided on the lives of the children of time" and "promulgate their ørlǫg". Frigg, on the other hand, while she "knows all ørlǫg", "says it not herself". ørlǫglausa "ørlǫg-less" occurs in Voluspa 17 in reference to driftwood, that is given breath, warmth and spirit by three gods, to create the first humans, Ask and Embla. Mentions of wyrd in Old English literature include The Wanderer, "Wyrd bið ful aræd" and Beowulf, "Gæð a wyrd swa hio scel!". In The Wanderer, wyrd is irrepressible and relentless. She or it "snatches the earls away from the joys of life," and "the wearied mind of man cannot withstand her" for her decrees "change all the world beneath the heavens".
The Wyrd Mons, a mountain on Venus, is named after an "Anglo-Saxon weaving goddess". According to J. Duncan Spaeth, "Wyrd is the Old English goddess of Fate, whom even Christianity could not entirely displace."
