uncivil

/ˈʌnˌsɪvəl/

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. Uncivil comes from the Latin root civilis, "relating to a society," or "befitting a citizen."
