Questions & Answers about On jouait avec le ballon, mais j'ai cassé une fenêtre.
How do we form the imparfait for jouait in this sentence?
Following the rule from this lesson, we take the nous form of the present tense and drop the -ons. For jouer (to play), nous jouons gives us the stem jou-. Since the subject is on, we add the third-person singular imparfait ending -ait to make on jouait.
Why is jouait in the imparfait tense, but ai cassé is in the passé composé?
Why does the translation say "We were playing" when the French uses on instead of nous?
In everyday spoken French, on is almost always used instead of nous to mean "we". Even though it means "we" in this context, on grammatically acts like "he" or "she". That is why it takes the third-person singular ending (-ait) rather than the nous ending (-ions).
Could I say avec la balle instead of avec le ballon?
