9 Grammatical Pitfalls
late 14c., from Old French espresser "press, squeeze out; speak one's mind" (Modern French exprimer), Medieval Latin expressare, frequentative of exprimere "represent, describe," literally "to press out" (source of Italian espresso; the sense evolution here is perhaps via an intermediary sense of something like "clay that takes under pressure takes the form of an image"), from ex- "out" (see ex-) + pressare "to press, push," from Latin premere (see press (v.1)). Related: Expressed; expresses; expressing.
late 14c., from Old French expres, from Latin expressus "clearly presented," past participle of exprimere (see express (v.)). This led to the noun (first attested 1610s) meaning "special messenger."
