Origin of uncivil

First recorded in 1545–55; un- 1 + civil

Explanation

If you're uncivil, you're not very polite. It's not okay to be uncivil to other people, even online. The original meaning of uncivil was a more extreme version of today's — it meant "barbarous." Now it simply means "not very nice" or "impolite." You might be excused for being uncivil to your younger brother if he's driving you crazy, especially if you've had a difficult day.
