Etymology: "Adversus" is the Latin source of the English word "adverse," and it is a grammatical form in its own right. Its core meaning is "turned against" or "facing toward," built from "ad" ("to, toward") and "vertere" ("to turn"), the same verb behind "vertex," "version," and "converse." The idea is literal: something turned toward you, and therefore facing you as an opponent. Latin used "adversus" as both a preposition and an adverb. As a preposition it governed the accusative case and meant "against," as in "adversus hostes," "against the enemies." Its ordinary function was spatial and hostile at once, so a Roman might describe a wind blowing against a ship or a soldier standing against an enemy line. English took the word largely through Latin legal and academic texts rather than everyday speech. The adjective "adverse" arrived in Middle English, and the preposition survives in phrases such as "versus," the abbreviation "v." that marks opposing parties in a lawsuit. The English prepositional form "versus" is in fact a direct descendant of the same Latin construction, not a separate coinage.
