Why do I need to know tu m’en veux?

Because not knowing what it means could lead to awkward misunderstandings..

What does it mean?

Tu m’en veux is put together by tu (you), me (me) and veux (want). If you aren't familiar with the expression, it looks like it reads ‘you me want’, which could have you thinking that it means ‘do you want me?’.

However there is nothing the slightest sensual about tu m'en veux.

On the contrary, tu m'en veux ? means ‘do you blame me?’ or ‘are you mad?’

It comes from s'en voulouir, which means 'to blame oneself'. You can also use it in the form vouloir à quelqu'un, which means 'blaming someone'.

It's a golden sentence to know, especially if you're in a couple with someone who is French (trust us, it will come in handy), but you can of course also use it with friends.

If you add a ne pas there you get Tu me n’en veux pas ? – You’re not mad, right?
