please help me translate eng to latin for a tattoo x

Ave Jadeladine,

Three things you have to bear in mind:
1. Latin cannot be transliterated directly into english, so it cannot be translated old english way or modern english way.
2. Online translators are tricky things - and often misleading, all those examples are grammatically wrong and ones hasn't translated at all.
3. Posterior is a world derived from latin and as is usually the case means something completely different (this makes it hard when learning latin as you first have to unlearn some things).

Try the following ...

Noli clunem meum videre => don't look at my butt
Noli clunem meum conspicere => don't watch/behold/catch sigh of my butt
Noli clunem meum contemplari => don't survey/regard/consider carefully my butt

Noli is singular (so you're only telling the one person not to look your butt)
Nolite is the plural (so you get to tell a whole roomful)

Noli/Nolite is the word the romans used for don't and it literally translates to be unwilling . Also, latin has NO word order as is in english so the line would translate literally to:

(Be unwilling) (butt) (my) (to look)

This is just so you know each word. Anyone who knows latin would understand it immediately as

Don't look at my butt

hope all this helps, and as always, get it checked by a few more latinists before getting it cut.

Vale.

Thank you mso much. Thats great
