Questions & Answers about Nous parlons souvent de ce livre.
Because the verb parler must agree with its subject nous (we).
In the present tense:
- je parle (I speak)
- tu parles (you speak, singular/informal)
- il/elle/on parle (he/she/one speaks)
- nous parlons (we speak)
- vous parlez (you speak, plural/formal)
- ils/elles parlent (they speak)
With nous, the correct ending is -ons, so you get nous parlons.
Yes. On parle souvent de ce livre is very common in spoken French.
- nous = we (more formal/standard, typical in writing and careful speech)
- on = literally “one,” but in everyday French it very often means we
Meaning-wise in conversation:
- Nous parlons souvent de ce livre. → neutral, a bit more formal
- On parle souvent de ce livre. → very natural, everyday spoken French
Grammatically, on always uses the il/elle form of the verb:
- On parle, not on parlons.
