A Liquid

1. A substance that is flowing, and keeping no shape, such as water; a substance of which the molecules, while not tending to separate from one another like those of a gas, readily change their relative position, and which therefore retains no definite shape, except that determined by the containing receptacle; an inelastic fluid.

Coordinate terms: solid, gas

Hyponyms: ideal liquid, non-ideal liquid

3. (phonetics) A class of consonant sounds that includes l and r.

Hypernyms: approximant, consonant

Coordinate term: glide

The differentiation of a liquid as an incompressible fluid is not strictly correct, experiment having shown that liquids are compressible to a very limited extent. See fluid.
