- stultify
- 1766, "allege to be of unsound mind" (legal term), from L.L. stultificare "turn into foolishness," from L. stultus "foolish" + root of facere "to make" (see factitious). The first element is cognate with L. stolidus "slow, dull, obtuse" (see stolid). Meaning "cause to appear foolish or absurd" is from 1809.
