- stab (v.)
- late 14c., "thrust with a pointed weapon," first in Scottish English, apparently a dialectal variant of Scottish stob "to pierce, stab," from stob (n.), perhaps a variant of stub (n.) "stake, nail," but Barnhart finds this "doubtful." Figurative use, of emotions, etc., is from 1590s. Related: Stabbed; stabbing.
