Etymology: "Convecting" is the present participle of "convect," a verb that English formed by working backward from "convection," the noun for heat moving through a fluid. The noun came first, built from the Latin "convectio," a "carrying together" formed from "convehere," "to bring together," which joins "con-" (together) and "vehere" (to carry). The Latin root survives in "vehicle" and "vehement," both of which share its sense of carrying or conveying. The verb is a back-formation: speakers took the ending "-tion" off the noun and treated what remained as a fresh verb stem, a process that regularly produces new verbs from nouns ending in "-ion." So the verb did not exist in Latin at all but was created in English to describe the action the noun names.
