可能來自PIE*skel,砍，劈，詞源同scale,clone,cleave.即一劈兩半，并不一定要求等分。

half

half: [OE] Half comes from prehistoric Germanic *khalbaz, which also produced German halb, Dutch half, and Swedish and Danish halv. If, as some have suggested, it is connected with Latin scalpere ‘cut’ (source of English scalpel and sculpture) and Greek skóloph ‘spike’, its underlying meaning would be ‘cut, divided’.

half

Old English half, halb (Mercian), healf (W. Saxon) "side, part," not necessarily of equal division (original sense preserved in behalf), from Proto-Germanic *halbaz "something divided" (cognates: Old Saxon halba, Old Norse halfr, Old Frisian, Middle Dutch half, German halb, Gothic halbs "half"), perhaps from PIE (s)kel- (1) "to cut" (see shell (n.)). Noun, adjective, and adverb all were in Old English.

Used also in Old English phrases, as in modern German, to mean "one half unit less than," for example tridda healf "two and a half," literally "half third." The construction in two and a half, etc., is first recorded c. 1200. Of time, in half past ten, etc., first attested 1750; in Scottish, the half often is prefixed to the following hour (as in German, halb elf = "ten thirty"). To go off half-cocked in the figurative sense "speak or act too hastily" (1833) is in allusion to firearms going off prematurely; half-cocked in a literal sense "with the cock lifted to the first catch, at which position the trigger does not act" is recorded by 1750. In 1770 it was noted as a synonym for "drunk."
