omasum (plural omasums or omasa)
Attested in the 1st century CE. Transmitted in Val. Max. 8, 1. damn. 8 a gloss τῇ τῶν Γάλλων γλώττῃ (tēî tôn Gállōn glṓttēi), from Gaulish. This leaves considered a borrowing from the Punic descendant of Proto-Semitic *ḥamṯ- (“abdomen”), since the voiceless pharyngeal fricative there would have been weakened by that time and southern Gaul was teeming with Punic colonies.
Second-declension noun (neuter).

The omasum, also known as the bible, the fardel, the manyplies and the psalterium, is the third compartment of the stomach in ruminants. Though its functions have not been well-studied, it appears to primarily aid in the absorption of water, magnesium, and the volatile fatty acids produced by rumen fermentation, that have not been absorbed into the bloodstream yet. The numerous folds of its mucosa are thought to trap digesta particles so that the maximum amount of nutrients may be absorbed.
