Learn French: Le vendredi soir, nous allons au cinéma. - On Friday evening, we go to the cinema.

In French, putting le before a day of the week means you do something regularly on that day. Le vendredi translates to "On Fridays" or "Every Friday." This shows it is a weekly routine.

If we go every Friday evening, why aren't vendredi and soir plural?

In English we say "Friday evenings" with an "s" at the end, but in French, the phrase le vendredi soir stays singular. The word le already does the job of showing that it happens every single time.

Why do we use au before cinéma?

The word au is a mandatory combination of à (to/at) and le (the). Because cinéma is a masculine word, you might expect to say à le cinéma, but French requires those two words to merge into au.

Does nous allons mean "we go" or "we are going"?

It means both! French only has one present tense. Depending on the context, nous allons can mean "we are going" (right now) or "we go" (as a regular habit). Because of Le vendredi, we know this is a regular habit, so "we go" sounds best in English.
