n. pl. o·men·ta (-tə) or o·men·tums One of the folds of the peritoneum that connect the stomach with other abdominal organs, especially: a. The greater omentum. b. The lesser omentum. [Latin ōmentum, perhaps a dialectal variant of *ūmentum (from earlier *ovimentum : *ov(i)-, to put on, cover; akin to -uere in Latin induere, to put on; see INDUMENTUM + -mentum, noun suffix) or perhaps from an Italic source akin to Umbrian umen and Latin unguen, fat, fatty substance (since the greater omentum is rich in fat), and Latin unguentum, salve; see UNGUENT.] o·mental (-təl) adj. |
