Bonjour
I guess you wanted to say :
"Comment t'appelles-tu ?"
It means "What is your name ?"
Its the inverted form to ask a question.
interrogative pronoun + verb + hyphen+ subject + ?
You can also say :
- Comment est-ce que tu t'appelles ? (using "est-ce que + subject + verb +?)
or
Tu t'appelles comment ? (raising the tone (intonation) when speaking)
hope this helps ☺☺☺
