Etymology: "Esplainer" is a recent informal coinage, not an old word, and its exact first use is hard to pin down. It is built on "explainer," with the "-splainer" ending borrowed from "mansplainer," which was popularized after Rebecca Solnit's 2008 essay "Men Explain Things to Me" gave the older "mansplain" wide currency online. The "es-" in "esplainer" likely comes from Spanish, as a playful nod to the Spanish verb "es" ("is") or to the Spanish-English mixing common in some online speech, but the precise intent varies by speaker. Because it appears mainly in casual online writing, it has no settled dictionary history, and its meaning is generally understood as someone who explains something in a condescending way.
