Etymology

From Middle French obtus (“obtuse (geometry); narrow-minded, obtuse; boring, dull, lifeless”), from Latin obt?sus (“blunt, dull; obtuse”), past participle of obtundere, from obtund?

(“to beat, strike; to bruise, crush, pound”) (ultimately from Proto-Indo-European *(s)tewd-, from *(s)tew- (“to hit; to push”)). More at obtund.
