Surface Forms

coolant singular
coolants plural

Morphology

coolant = cool (transparent) = cool + ant

Formed by adding the noun-forming suffix '-ant' to the verb 'cool'; meaning 'a substance that cools' is directly derivable.

Etymology

Coolant comes from the simple word cool, meaning 'not warm', plus the ending -ant that makes it into 'a thing that does something'. So a coolant is literally something that 'cools' a machine or engine by taking heat away.
