ruminant
ROO-muh-nuhnt
/ˈruː.mɪ.nənt/
An even-toed ungulate mammal that chews the cud regurgitated from its rumen (e.g., cows, sheep, goats, deer).
Refers to animals with a specialized four-compartment stomach designed to ferment plant material before digestion.
The story behind the word. From the Latin ruminare, meaning 'to chew the cud.' This verb comes from rumen, the first stomach chamber of these animals. The root suggests a slow, repetitive process, which is why 'ruminate' also means to ponder deeply.

Memory hook
Ruminants 'ruminate' (chew over) their food, just like people 'ruminate' (think over) their thoughts. Ruminants chew and chew again.
When not to use
Do not use for non-cud-chewing herbivores like horses, rabbits, or pigs.
Fun facts
- Ruminants spend up to eight hours a day chewing their cud to break down fibers for digestion.
