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?

In the sentence "il suffit d’observer ce que font les autres et les imiter," why have the verb (font) and the subject (les autres) swapped places? Shouldn't it be "il suffit d’observer ce que les autres font et les imiter"?

The sentence is taken from this text: "https://www.lawlessfrench.com/listening/bise-a-la-francaise/"

Thank you in advance. 

Why is "elle doit partir, ce qu'est triste"  wrong 

Contracting "Ce qui" 

I just want to clarify can the following be either, 'what is this' or 'what is that?' If not, how do you change the sentence to be one or the other?

Or is it it for example:

qu'est-ce que c'est : What is that?

qu'est-ce que c'est que cela: What is this?

Considering the general tendency to drop ne in spoken French, could it also be omitted in the examples used in the lesson? For example, would the sentence « Tu as peur qu’il parte » still make sense? Is it grammatically incorrect without the ne or does its meaning change when ne is dropped?

If I am trying to say Amongst all the sports, I like playing ______ the least or I don't like playing _____ the most, which one(s) of the following forms are correct? Is it a superlative with verbs or with nouns?

Je n'aime pas jouer au foot le plus.

J'aime jouer au foot le moins.

J'aime le moins jouer au foot.

Je n'aime pas le plus jouer au foot.
