Syn. — Rude; officious; intrusive; saucy; unmannerly; meddlesome; disrespectful; impudent; insolent. — Impertinent, Officious, Rude. A person is officious who obtrudes his offices or assistance where they are not needed; he is impertinent when he intermeddles in things with which he has no concern. The former shows a want of tact, the latter a want of breeding, or, more commonly, a spirit of sheer impudence. A person is rude when he violates the proprieties of social life either from ignorance or wantonness. "An impertinent man will ask questions for the mere gratification of curiosity; a rude man will burst into the room of another, or push against his person, inviolant of all decorum; one who is officious is quite as unfortunate as he is troublesome; when he strives to serve, he has the misfortune to annoy." Crabb. See Impudence, and Insolent.
