Latin
Etymology 1
From Proto-Indo-European *sinos; akin to Albanian gji ‘breast, bosom’.[1]
The mathematical sense ‘chord of an arc, sine’ was introduced in the 12th century by Gherardo of Cremona as a semantic loan from Arabic جَيْب (jayb, “chord, sine”) (ultimately a loan from Sanskrit ज्या (jyā, “bowstring”)) by confusion with جَيْب (jayb, “bosom, fold in a garment”).

- (Classical) IPA(key): /ˈsi.nus/, [ˈs̠ɪnʊs̠]
