อัตวินิบาตกรรม ภาษาอังกฤษ

First attested in Thomas Browne's Religio Medici (1643) in noun sense 1, ostensibly from New Latin suīcīdium, from suī (genitive reflexive pronoun) + -cīdium (“act of killing or murder”), but often believed to have originated in English before entering Latin. Displaced native Middle English seolf-cwale from Old English selfcwalu (literally “self-slaughter”), after which suicide may have been modelled, or calqued (compare manuscript). Noun sense 3 is perhaps by analogy with words like homicide, patricide (see -cide), or, although unlikely, from Medieval Latin suīcīda; see the Etymology section at suīcīdium.
