French has two common ways to say “we”:

• nous
• on

Both can mean the same thing in many cases. Yet they do not sound the same. The choice changes the tone, the level of formality, and sometimes the sense of the sentence.

In modern spoken French, on is far more common than nous. In formal writing, speeches, school essays, and careful speech, nous still has a strong place.

The basic difference

Nous

Nous is the traditional and formal word for “we.”

It uses the normal first person plural verb form.

Examples:

• Nous parlons français. “We speak French.”
• Nous allons partir demain. “We are going to leave tomorrow.”
• Nous avons déjà vu ce film. “We have already seen this film.”

This form is common in:

• formal writing
• school writing
• official speech
• careful public speaking
• literature
• formal letters

It can also sound more serious, more distant, or more deliberate.

On

On originally meant “one” in the sense of “people in general.” Over time, it also came to mean “we.”

When on means “we,” the verb stays in the third person singular form.

Examples:

• On parle français. “We speak French.”
• On va partir demain. “We are going to leave tomorrow.”
• On a déjà vu ce film. “We have already seen this film.”

This is the normal choice in everyday spoken French.

Verb agreement

This is one of the biggest differences.

With nous

The verb uses the nous form.

Examples:

• Nous mangeons ici. “We eat here.”
• Nous sommes prêts. “We are ready.”
• Nous faisons attention. “We are being careful.”

With on

The verb uses the third person singular form, like il or elle.

Examples:

• On mange ici. “We eat here.”
• On est prêts. “We are ready.”
• On fait attention. “We are being careful.”

Even though on means “we,” the verb stays singular.

Agreement of adjectives and past participles

This area often confuses learners.

When on means “we,” speakers often make adjectives plural in meaning, even though the verb is singular.

Examples:

• On est prêts. “We are ready.”
• On est contentes. “We are happy.” said by a group of women
• On est fatigués après le voyage. “We are tired after the trip.”

In speech, this agreement is easy to hear. In writing, people sometimes avoid it in very formal contexts because it mixes singular grammar with plural meaning.

With nous, agreement is fully regular.

Examples:

• Nous sommes prêts.
• Nous sommes contentes.
• Nous sommes fatigués après le voyage.

Why on became so common

Spoken French tends to prefer shorter and simpler sound patterns.

The nous verb forms are often longer and heavier:

• nous parlons
• nous faisons
• nous voulons

The on forms are shorter:

• on parle
• on fait
• on veut

Over time, everyday speech shifted strongly toward on.

Today, many native speakers use nous very little in casual conversation except in fixed phrases or for emphasis.

Formal and informal tone

On sounds natural and relaxed

In daily speech, on is usually the safest choice.

Examples:

• On va au cinéma ce soir ? “Are we going to the cinema tonight?”
• On prend le train ? “Shall we take the train?”
• On a faim. “We are hungry.”

Using nous in such cases may sound stiff, formal, or old-fashioned.

Nous sounds more formal or careful

Examples:

• Nous vous remercions de votre patience. “We thank you for your patience.”
• Nous souhaitons vous informer que… “We wish to inform you that…”
• Nous avons le plaisir de vous annoncer… “We are pleased to announce…”

This style is common in:

• business French
• public notices
• formal emails
• speeches
• academic writing

In writing

Informal writing

In text messages, online chat, and casual emails, on is very common.

Examples:

• On se voit demain ? “Shall we see each other tomorrow?”
• On arrive dans dix minutes. “We are arriving in ten minutes.”

Formal writing

Formal writing usually prefers nous.

Examples:

• Nous examinerons cette question plus tard. “We will examine this question later.”
• Nous estimons que cette décision est juste. “We believe that this decision is fair.”

Still, modern journalism and less formal writing sometimes use on to sound closer to normal speech.

Inclusive and exclusive meaning

Usually, both nous and on simply mean “we.” Yet context matters.

Sometimes on feels broader and less sharply defined.

Example:

• En France, on mange souvent du pain. “In France, we often eat bread.”

Here on can mean:

• “we French people”
• “people in France”
• “people in general”

Using nous here would sound strange unless the speaker is speaking for a clearly defined group.

On meaning “people,” “someone,” or “they”

This is important because on does not always mean “we.”

Examples:

• On frappe à la porte. “Someone is knocking at the door.”
• On dit que ce restaurant est excellent. “People say that this restaurant is excellent.”
• En Angleterre, on conduit à gauche. “In England, people drive on the left.”

In these cases, nous cannot replace on.

Using nous for emphasis

Sometimes speakers use nous to sound stronger, more serious, or more united.

Examples:

• Nous, nous refusons cette idée. “We refuse that idea.”
• Nous voulons des changements. “We want changes.”

Politicians, leaders, and public speakers often prefer nous for this reason.

Mixed use in real speech

French speakers often move between the two forms.

Example:

• Nous avons décidé qu’on partirait demain. “We decided that we would leave tomorrow.”

This is normal and natural.

The first part sounds more formal or deliberate. The second sounds more conversational.

Fixed expressions with nous

Some expressions almost always use nous.

Examples:

• Chez nous “At our place” or “in our country”
• Entre nous “Between us”
• Nous deux “The two of us”

Commands and suggestions

French often uses on for suggestions in speech.

Examples:

• On y va ? “Shall we go?”
• On commence ? “Shall we start?”
• On mange dehors ce soir ? “Shall we eat outside tonight?”

Using nous here is possible but more formal:

• Commençons. “Let us begin.”
• Allons-y. “Let us go.”

Regional and social variation

The use of on for “we” exists across the French-speaking world.

In many places, especially in spoken French, it is the dominant form.

Some speakers use nous more often in careful speech, education, politics, or formal settings. Older speakers may also use it more than younger speakers.

Common learner mistakes

Using nous everywhere

Many learners first learn nous as “we” and use it in all situations.

This is grammatically correct, but it may sound overly formal in casual conversation.

Forgetting the singular verb with on

Incorrect:

• On parlons français.

Correct:

• On parle français.

Forgetting plural agreement in meaning

When on means “we,” spoken French often uses plural adjectives.

Examples:

• On est contents.
• On est arrivés.

Comparing the two directly

Everyday conversation

Natural:

• On va prendre un café. “We are going to get a coffee.”

More formal:

• Nous allons prendre un café.

Formal announcement

Natural formal style:

• Nous vous remercions de votre soutien. “We thank you for your support.”

Too casual for many formal settings:

• On vous remercie de votre soutien.

General statements

Natural:

• En été, on mange plus léger. “In summer, we eat lighter food.”

Less natural:

• En été, nous mangeons plus léger.

Alternatives and related expressions

French sometimes avoids both nous and on.

Group nouns

Examples:

• L’équipe va partir demain. “The team is going to leave tomorrow.”
• La famille arrive ce soir. “The family is arriving tonight.”

Passive style

Examples:

• Le projet sera terminé demain. “The project will be finished tomorrow.”

This avoids saying who “we” are.
