Bon vs. Bien How to Say “Good” in French
In English, we often use “good” for both direct description and for giving our opinion about an experience. In French, you have two main options: bon and bien. They don’t always match up exactly with “good” and “well,” and that’s where the confusion starts. You can download a free PDF of this lesson guide in my private French Grammar Library.
| word | part of speech | main use | example |
| bon (masc.) bonne (fem.) | adjective | Describes a noun directly (a good thing) | C’est un bon film.It’s a good movie. |
| bien | adverb(sometimes used adjectivally after être) | Describes the quality of something, your impression, or how it works | Le film est bien.The movie is good. (I like it.) |
Bon
Attaches to the noun (before the noun).
You’re talking about the inherent quality of the thing.
Bien
Attaches to the verb or to the situation/experience.
You’re giving an opinion about how it is, functions, or feels.
| BON / BONNE (adjective before noun) | BIEN (after être or a verb) |
| C’est un bon livre.It’s a good book.(quality of the book) | Ce livre est bien.This book is good.(I like it) |
| C’est une bonne idée. That’s a good idea. | L’idée est bien.The idea works well.(It’s fine) |
| C’est un bon restaurant. | Ce restaurant est bien. This restaurant is good / nice. |
| C’était un bon concert. | Le concert était bien.The concert was good / enjoyable. |
Why is it tricky?
In English, “The book is good” could mean:
It’s a good book (inherent quality = bon).
I enjoyed it / it works well (overall impression → bien).
French forces you to make the choice, so you have to decide:
Am I directly describing the noun? If so, use “bon”.
Am I giving my impression of the experience or situation? If so, use “bien”.

Keep it simple with these quick tips
Bon
Think: “good + noun” (bon vin, bonne idée, bon moment)
Bien
Think: “good + how it is / how it works” (ça marche bien, c’est bien)
If you could replace “good” with “enjoyable” or “fine,” bien is often the right choice.
