synonymous or separate?

Question

The lesson states that using the pronoun "on" is equivalent to using the pronoun "nous" to indicate "we", but when appearing in a quiz it says that using "nous" is incorrect and "on" is correct. If there is a significant difference in usage, then it should be explained in the lesson, as it fails to do so. If it states that they are synonymous and exchangeable in use, then correction needs to be to that effect. I can't learn how to use them for what they mean when in dictation they are one thing but are another thing entirely when put into practice.

Accepted Answer

In meaning, they are interchangeable, however they are not followed by the same verb conjugations:  we are = "nous sommes" = "on est" (same form as "il/elle")

Answer

Bonjour Matthew,

Can you please post an example of a case where "on" was marked incorrect? It may have been a simple matter of verb conjugation - if the question was something like "___ habitons ici depuis 10 ans," the answer can only be "nous" due to the conjugation habitons.
