lui and la

So in the last lesson, we used LUI - as in," Nous devons lui acheter un cadeau."  We must buy her a gift.

And in this one, they introduce the verb TUTOYER - -  

in the example they say "You can use tu with her"  -" Vous pouvez la tutoyer"

why isn't it, "vous pouvez lui tutoyer" - ?

thanks!

Hi booksoutloudhfx,

I'm afraid you posted your question in the wrong forum, because this section is for questions on Italian grammar. Sadly I don't speak any French, or I'd gladly help you out!
