What does ruminant mean?
A ruminant is a hoofed mammal that chews cud: food is partly digested in the stomach, returned to the mouth, and rechewed before digestion continues. This process helps animals obtain nutrients from fibrous vegetation such as grass and leaves. Cattle, sheep, goats, deer, and related animals are familiar ruminants. The word can also be used figuratively of a person who reflects deeply or considers an issue at length, although that usage has a more literary and formal tone. As an adjective, ruminant can describe the animals themselves, their digestive systems, or characteristics associated with them. The term is useful in biology, agriculture, veterinary science, and food production, where the distinctive digestive process of these animals is important. In general speech, “cud-chewing animal” is understandable, but “ruminant” is the precise scientific and agricultural term.

Where does ruminant come from?
Ruminant comes through Latin from roots associated with rumen, meaning “belly,” and ruminari, meaning “to chew cud.” The word entered English in the early modern period and was initially associated with animals that chew cud. English ruminate, rumination, and ruminative belong to the same Latin family, developing meanings connected both with chewing cud and with turning thoughts over repeatedly.
