Etymology: "Oppugnant" is an adjective meaning hostile to authority, and it comes straight from Latin "oppugnans," the present participle of "oppugno," a verb meaning to attack or assault. Its parts are easy to read: "ob-" (against) and "pugno" (to fight), the same root that gives English "pugnacious" and "impugn." The Latin verb originally carried a physical sense of storming or fighting against a position, and the English adjective keeps that combative edge. Because "oppugnant" sits so close to "impugn" in both sound and sense, readers often mistake the two. "Impugn" means to call into question a person's honour or a claim's truth, while "oppugnant" describes a standing opposition to authority itself. The shared root links them, but the English words took different paths from the same Latin fighting verb.
