The english word sine comes from a series of mistranslations of the sanskrit jya- ardha, which means chord-half. Aryhabata ( fth century) frequently abbreviated this term to jya or its synonym jiva. When some of the hindu works were later translated into arabic, the word was simply transcribed phonetically into an otherwise meaningless. But since arabic is written without vowels, later writers interpreted the consonants jb as jaib, which means bosom or breast. Arabic trigonometry work was translated into latin, the translator used the equivalent. Latin word sinus, which also meant bosom, and by extension, fold (as in a toga over a breast), or a bay or gulf.
