Etymology: "Usurpant" is a rare English noun for someone who seizes power or position without any right to it. It comes straight from the Latin "usurpans," the present participle of "usurpare," meaning "to seize for use" or "to take possession of." That verb was itself built from "usus" (use) and "rapere" (to seize), so the core idea is grabbing something for one's own employment. The "-ant" ending, which marks an active participle, is the same ending found in English words like "assistant" and "attendant," and the noun form simply turns the participle into a name for the person doing the seizing.
