To rebuke or snub someone sharply; to check or stop something abruptly (archaic or dialectal).
From Middle English, possibly connected to Old Norse 'sneypa' meaning to rebuke or shame. The word is rare in modern English but appears in classic literature.
J.K. Rowling chose 'Snape' as a surname for Professor Severus Snape precisely because the word means to snub or rebuke—a perfect fit for the character's cold demeanor.
