Pronunciation

 * In early poetry, the first syllable of this word (or that of the derived adjective ) generally occurs in an anceps position, which would allow either a light or heavy syllable. The scansion cŏtīd-, with unambiguously light cŏ-, seems to be first attested in (11, 1, 2). The second syllable normally scans heavy, but the scansion cōtĭd- (or cottĭd-) is found in the manuscripts of  68, 139: "flagrantem cotidiana/quotidiana/cottidiana". (However, it has been suggested this should be emended to something else like "contudit iram", "condidit iram" or "concoquit iram".)
