Etymology: In Latin, "oppugnare" was a physical word. It meant to assault, storm, or besiege a place. It is built from "ob," meaning "against," and "pugnare," meaning "to fight." That second element comes from "pugnus," the fist, so the underlying picture is of striking at an opponent. The sense of arguing against a claim is a metaphor. A flawed statement is treated like a fortress to be attacked with evidence and reasoning. English borrowed the word from Latin with its figurative sense already available, and it remains rare, mostly in formal or literary writing. Its close relative "impugn," from the same root "pugnare," is far more common and carries the same idea of attacking a claim or a person's reputation.
