More example sentences

English speakers adopted both "impertinent" and "pertinent" from Anglo-French in the 14th century. Both words derive from the present participle of the Latin verb "pertinēre," meaning "to pertain." Initially, "impertinent" was used for things that are simply not relevant. Over time, it came to be used of things that are not only irrelevant but rudely or inappropriately so, and later for people who are just straight-out rude.
