Civitas mail ntust

It seems like you're trying to communicate something in Latin!

"Civitas" means "city" or "state" in Latin.

"Mail" is not a Latin word, but I'm assuming you meant to say "mutare" which means "to change" or "to move".

"NTUST" is not a Latin word or phrase, but it looks like it might be a typo or a code.

Could you please provide more context or clarify what you're trying to say? I'd be happy to help you with your Latin phrase or sentence!
