Picture the word arriving in English in the 1530s, carrying a Latin recipe for lifting someone’s spirits: ex-, with its sense of “out” or “thoroughly,” joins hilarō, “to cheer.” The cheerfulness inside hilarō came through Greek ἱλαρός, “merry,” and reaches back, according to Wiktionary, to a reconstructed root meaning “comfort, mercy.” That makes the word’s history feel less like a passing giggle and more like being brought out of gloom into kindness. Its close cousin hilarity keeps the same bright Greek inheritance, while ex- also turns up in words such as exuberant and exclaim. Exhilarate is, quite literally, a word for cheering someone up from the inside out.
