Etymology: The Latin root behind "refrigeration" is "refrigerare", meaning "to cool down", built from "frigus", "cold", and the prefix "re-", which here intensifies the verb rather than meaning "again." English took the verb "refrigerate" first, and the noun grew from it by adding the common suffix "-ion", which turns an action verb into the name of the process itself. The word is a plain example of a learned formation: a scholarly coinage assembled from classical parts, rather than a term that passed through everyday speech for centuries. Its core idea, drawing heat out of something to keep it from spoiling, is far older than the word, but the English vocabulary to name it came later, once cooling became a matter of machinery rather than ice, cellars and snow.

Synonyms: cooling, chilling
