The word "expression" originates from the Latin exprimere ("to press out, represent"), combining ex- (out) + primere (to press). The metaphorical sense of "pressing out" thoughts or emotions evolved into its modern meanings of verbal or nonverbal communication. The suffix -ion nominalizes the action, solidifying its role as a noun in English.
