Sense 1. Not pertinent; not pertaining to the matter in hand; having no bearing on the subject; not to the point; irrelevant; inapplicable; misplaced. “Things that are impertinent to us, and do not concern us.” Tillotson.
It will appear how impertinent that grief was which served no end of life. Bp. Taylor.

Synonyms—Rude; officious; intrusive; saucy; 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, in violation 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. “I was forced to quit my first lodgings by reason of an officious landlady, that would be asking me every morning how I had slept.” Addison.
