Etymology

The word "idiomatic" derives from the Greek "idiōmatikos," meaning "peculiar to a language." The root "idiom" originates from Greek "idiōma" (private property, peculiar phrase), from "idios" (one's own, private). The suffix "-atic" (via Latin "-aticus") forms adjectives, indicating a relationship to the root. Over time, "idiomatic" evolved to describe language use that feels natural to native speakers, reflecting cultural and linguistic nuances.

  3. "Hit the hay" is an idiomatic phrase meaning "go to bed."
