- excuse (v.)
- early 13c., "attempt to clear (someone) from blame," from Old French escuser (12c., Modern French excuser) "apologize, make excuses; pardon, exonerate," from Latin excusare "excuse, make an excuse for, release from a charge," from ex- "out, away" (see ex-) + causa "accusation, legal action" (see cause).
Meaning "to obtain exemption or release" is from mid-15c.; that of "to accept another's plea of excuse" is from early 14c. Excuse me as a mild apology or statement of polite disagreement is from c.1600.
