indirect object/direct object

Question

I do not understand how the following sentence requires 'avoir'. Et alors, tu ________ retourné lentement tes cartes...

I would have thought that 'tes cartes' is an indirect object because the word 'lentement' sits between the verb and the object. Or is it that 'lentement', being an adverb, is treated as part of the verb, and therefore 'tes cartes' is the direct object of the compound verb 'retourné lentement'?

Accepted Answer

Hi Tim
The verb 'retourner' in this example is transitive -
retourner quelque chose = to turn something over

J'ai retourné mon matelas ce matin = I turned my mattress over this morning
Tu as retourné les cartes ... = You turned the cards over ...

'les cartes' is a direct object.
