Etymology: "Concurrently" is a plain formation: the adjective "concurrent" plus the adverbial suffix "-ly". "Concurrent" comes from Latin "concurrere," meaning "to run together" or "to meet," built from "con-" ("together") and "currere" ("to run"). The idea of two things running side by side in time gave the adjective its sense of happening at once. The suffix has a long history of its own. It descends from the Old English "-līce," which was itself linked to the noun "lic" ("body" or "form"), and it was reduced to "-ly" in Middle English. Attaching it to a Latinate adjective like "concurrent" is one of the most ordinary ways English builds adverbs, so the word's construction is entirely regular.

Synonyms: simultaneously, together, at the same time, synchronously, coexistently
