Questions & Answers about L'opérateur demande quand vous avez reçu la commande.
Why isn't there an inversion like quand avez-vous reçu?
Because this is an indirect question. When you report a question using words like quand, où, or pourquoi, you must use the standard subject-verb word order (vous avez). You also drop any est-ce que that might have been used in the original direct question.
Since this is reported speech, why didn't the tense of avez reçu change?
In French, the tense of the reported speech only shifts backwards if the main reporting verb is in a past tense. Here, the introductory verb demande is in the present tense, so the original tense of the question (passé composé) stays exactly the same.
Why use commande for 'order' instead of ordre?
What verb does reçu come from?
It is the past participle of recevoir (to receive). Verbs ending in -cevoir are irregular and typically have past participles ending in -çu.
