To consume food ornourishment, with a strong emphasis on the body's ability to ingest, process, and derivesustenance from it; to eat for functional nourishment rather than for pleasure.
The term is distinct from a general word for "eat" (e.g.,hie). Whilehie describes the action itself,leiliu focuses on the physiological process and outcome of eating.
It is most commonly used in negative constructions (not leiliu-ing) to describe an inability to eat due to illness, fatigue, or a lack of available sustenance, leading to physical depletion.
