Etymology: "Expresser" is simply "express" with the agent suffix "-er" attached, so it means one who expresses. Its base, "express," comes from the Latin "exprimere," meaning "to press out," built from "ex-" (out) and "premere" (to press), which is why the core idea of expressing has to do with squeezing something out into the open. The suffix "-er" does the work of turning the verb into a noun for the person or thing doing the action. The same pattern produces "presser" or "squeezer," and "expresser" fits that pattern exactly, so it is a transparent formation rather than a word with a separate history of its own.

Synonyms: speaker, communicator
