nous/on

Question

why in this exercise is the nous form used one time and the on form another when they are both times speaking about what they will do together?

Accepted Answer

The “nous” form and the “on” form are interchangeable for “we”, and can be used together, even in the same sentence. (In everyday spoken language the “on” form seems to be by far the most common). I can’t see where the “nous” form is used in his exercise, unless you mean the imperative “Commençons ...“ which means “Let us commence ...” There is no alternative way to say that.
