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”).
Pronunciation
- (Classical Latin) IPA(key): /ˈsi.nus/, [ˈs̠ɪnʊs̠]
- (modern Italianate Ecclesiastical) IPA(key): /ˈsi.nus/, [ˈsiːnus]

‘et mēcum plēnōs flōrē refertē sinūs.’- ‘‘Come, my companions,’’ she said,
‘‘and with me you all [can] carry back flowers, filling the folds of your garments.’’
(Persephone and her attendants wander away from the protection of her mother Ceres and the other matrons prior to Persephone’s abduction.)
- ‘‘Come, my companions,’’ she said,
