I thought questions could be asked in statement form, so I put "Vous entrez pourquoi?" and was marked wrong. Is it not acceptable to place pourquoi at the end of a question? I don't care about being marked wrong. I just want to learn what's right.
The word "Entrer" is an -er verb and most -er verbs have a set of endings depending on the subject. The -er ending for"vous" is -ez it will never be just an -e. Other words like "Je", "Il", "Elle" and "On", they have endings that end with -e.
