When you do something imprecisely, you do it in a way that is not exact. The number, the word, or the edge is a little off — not wrong on purpose, just not sharp. People use this when they want to be fair: the idea may be right, but the details are fuzzy. Teachers, scientists, and careful writers use it a lot, because they care how close a measurement or a description is. In everyday talk, people more often say “not exactly” or “roughly”; imprecisely sounds a bit more careful and formal. It is the adverb from imprecise, so it goes with a verb: you speak imprecisely, measure imprecisely, remember something imprecisely. Though actually, we all talk imprecisely most of the time — ordinary language is rarely as neat as a ruler.
