Did You Know?

You probably won't be surprised to learn that "exponent" shares an ancestor with "proponent" - and indeed, the Latin ponere ("to put") is at the root of both terms. "Exponent" descends from "exponere" ("to explain" or "to set forth"), which joins "ponere" with "ex-" ("out"). "Proponent" traces to "proponere" ("to display" or "to declare"), from "ponere" and "pro-" ("before"). "Proponent" can describe someone who offers a proposal (it's related to "propose," which also ultimately comes from "proponere"), but today it usually means "one who argues in favor of something." "Exponent" can also refer to someone who is an advocate, but it tends to refer especially to someone who stands out as a shining representative of something, and in addition it has retained its earlier meaning of "one who expounds."
