Armscye


In sewing, the armscye is the armhole, the fabric edge to which the sleeve is sewn. The length of the armscye is the total length of this edge; the width is the distance across the hole at the widest point.

Etymology

Multiple theories for the etymology of "armscye" have been proposed.
The scholarly etymology has the origin as "arm" + "scye." The first documented use of "scye" in print is by Jamieson Suppl.: "sey," a Scots and Ulster dialect word meaning ‘the opening of a gown, etc., into which the sleeve is inserted; the part of the dress between the armpit and the chest.
A more fanciful folk etymology is as follows. Because the expression "arm's eye" was used in some older sewing texts it is conjectured that in poor prints the apostrophe and the crossbar of the lower case "e" were indistinct, and the neologism "armscye" was created by readers who concatenated the orphaned fragments "arm" and "s" with the corrupt "cye". According to this undocumented theory, until the beginning of the 20th century writers favoured the original term or at least a more logical variation, but as self-proclaimed experts copied each other, the term "armscye" eventually became widely enough used by home sewers to gain general acceptance.
The latter theory clearly contradicts evidence that the term "scye" was already in use at least as early as 1825. Therefore, the erroneous folk analysis was not in the direction from "arm's eye" to "armcye", but rather from the original "armcye" to "arm's eye".
