Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

lactes, ium (in sing. lactis, is, only, acc. to Prisc. p. 686, erroneously on account of lactis agninas), f. [root lag-; Gr. λαγαρός; cf. Lat. languidus, laxus], the intestines; esp. the smaller intestines, chitterlings (anteclass. and post-Aug.): ab hoc ventriculo lactes in homine et ove, per quas labitur cibus: in ceteris hillae, Plin. 11, 37, 79, § 200: ita cibi vocivitate venio lassis lactibus, i. e. empty, famished, Plaut. Curc. 2, 3, 40: pulmone et lactibus unctis, Pers. 2, 30.
Prov.: adligare canem fugitivom agninis lactibus, said of the employment of a trifling remedy for a great evil, Plaut. Ps. 1, 3, 85.
