French language Q&A Forum

When I wrote "à vélo" I received a correction that I should have written "en vélo." However, I was under the impression that both "en vélo" or "à vélo" are acceptable (see: À/en + [means of transportation] (French Prepositions)). Was this an error or is there a reason that "à vélo" is not acceptable here?

Can’t there be two correct answers to this statement about France’s territory depending on whether you are referring to ‘the territory’ or the territories ‘climate and relief’?

I wrote "Notre Salade aux Trois Fromages est [...] et assez copieuse" which was marked as incorrect. Looking at Le Robert, copieux is given as a synonym of consistant so I'm wondering why?

Does copieux mean more that the dish is physically large (ie a lot of food) whereas consistant just means it's filling but doesn't given any indication to the size of the meal?

Can you say that hamburger was “grand” instead of “gros ? What is the difference between these 2 adjectives?

Is it as simple as J'ai honte d'avoir peur des chats?

I cannot quite figure out why the verb 'remplir' is in the form 'remplis'. Is it because 'remplis' is used as an adjective?

Please explain why the given answer is "Alain lui a plaire tout a suite"   which to me says Alain likes him...  Its not like il manque is it.

I understand from the disucssion that you can use depuis with the present tense or passé composé but I have this question:

Depuis quand est-ce que vous êtes vous mariés ? ( a point in time in the past)

Asking a person who is married how long they've been married (and still are): Vous êtes vous mariés depuis 30 ans? (Past tense so does this mean they're no longer married?)  or, should you say, Vous êtes mariés depuis 40 ans? (still married).

This always trips me up so thank you ahead of time for your help!
