In plain English: A liquid is a substance that flows and takes the shape of whatever container it is poured into.

Usage: Use "liquid" as a noun specifically for substances like water or oil that flow freely and take the shape of their container. Do not use it to describe solid objects or abstract concepts unless referring to financial assets or stocks.
existing as or having characteristics of a liquid; especially tending to flow

Flowing freely like water; fluid; not solid and not gaseous; composed of particles that move freely among each other on the slightest pressure.

In plain English: Liquid describes something that is not solid and can flow freely, like water or juice.

Usage: Use "liquid" as an adjective to describe substances that flow freely and take the shape of their container while maintaining a definite volume, such as water or oil. Avoid using it to mean "plentiful" or "abundant," which is a common misuse derived from its metaphorical sense in phrases like "liquid assets."
The word liquid entered English from Old French and Latin, originally describing something that is fluid or moist. It later took on a specialized meaning in linguistics to refer to a specific type of consonant sound.
