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