Etymology: "Omasal" is an adjective meaning of or relating to the omasum, the third stomach of ruminant animals such as cattle, sheep and goats, the one often called the "bible" or "many-plies" for its layered, leaf-like folds. The word is formed from "omasum" with the adjectival suffix "-al", the same pattern that gives English words like "gastral" or "ventral" from their Latin-derived stems. The underlying noun, "omasum", is a New Latin coinage rather than a word from classical antiquity, so Roman writers never used it for the stomach of a cow. Its base is the Latin "omasum", a term that scholars of the period used for the paunch of an animal, and English anatomists borrowed it as a technical name for this specific chamber. The suffix does the rest: anatomists needed a plain adjective to describe the tissues, vessels and conditions belonging to that organ, and "omasal" supplied it.
