Sinus

(κόλπος). Literally any surface bent into a hollow or semicircular form. Hence (1) a loose fold in a garment, usually made so as to lie across the breast (hence sinus, also meaning the breast), and used as a pocket for carrying any small object, as a letter, a purse, etc. (Cic. Verr. i. 5, 57);

(2) the bosom of a sail;

(3) a bay or gulf on a coast;

(4) a round vessel for wine or milk. See sinum.
