Etymology
Etymology Information

'coolant' originates from modern English, formed from the verb 'cool' + the suffix '-ant' (from French '-ant', ultimately from Latin '-ans'), where '-ant' marks an agent or something characterized by an action.

Historical Evolution

'cool' comes from Old English 'cōl' meaning 'not warm'; the agentive/adjectival suffix '-ant' was borrowed from French/Latin forming 'coolant' in modern English (term became common with industrial/engineering usage in the 19th–20th centuries).

Meaning Changes

Initially it meant 'that which makes cool' (a general agent of cooling); over time it specialized to mean substances or fluids used specifically for heat transfer and temperature regulation in machines and systems.
