Breviloquent means using few words, and the joke writes itself: the word is twelve letters and four syllables long, from Latin brevis (short) and loqui (to speak), on record since 1865. A.Word.A.Day lists its neighbours for every other way of talking — magniloquent for the pompous, somniloquy for talking in your sleep, sialoquent for the ones who spray. Town & Country used it straight in 2012: “For once, the exchange was breviloquent.”
