Using 'On' as 'We': Casual Past Tense Agreement
on means 'we', use singular verbs but plural past participle endings with être verbs.
Grammar Rule in 30 Seconds
In casual French, use 'on' instead of 'nous' to mean 'we', but remember to conjugate the verb in the third-person singular.
- Replace 'nous' with 'on' for 'we' in daily conversation: 'On a mangé' (We ate).
- Always conjugate the verb as if the subject were 'il/elle': 'On est allé' (We went).
- Agreement: If 'on' refers to a group of people, add an 's' to the past participle: 'On est allés'.
Overview
Ever felt like nous is too formal for a quick text to your group chat? Like you’re wearing a three-piece suit to a casual pizza hang? That’s where on comes in.
It is the ultimate French life hack. In modern French, we almost never say nous when we’re hanging out with friends. We use on.
It’s faster, shorter, and honestly, it just sounds cooler. But here’s the twist: even though on acts like a single person when you conjugate the verb (like il or elle), it remembers it’s actually representing a group when it comes to the past participle. Think of it like a secret agent.
On the outside, it looks like a singular 'he' or 'she'. On the inside, it’s a whole squad of 'we'. If you’ve ever been confused about why a singular-looking sentence has a plural ending, don't worry.
You’re not seeing double. You’re just seeing the 'secret plural' in action. It’s like when a toddler tries to hide three other toddlers under a giant trench coat.
They might look like one tall person, but if you look at the shoes, you’ll see four pairs of sneakers. That’s on for you. It’s the grammar equivalent of a group hug that only needs one seat on the bus.
Why work harder with nous sommes partis when you can just breeze through with on est partis? It’s the lazy student’s dream, but with a tiny bit of fashion police work at the end of the verb. If you’re planning to post an Instagram story of your weekend trip to Lyon, you’re going to need this rule.
Otherwise, your French friends might think you traveled alone, or worse, they’ll think you’re a 19th-century aristocrat. And let's be real, nobody wants to be the person who brings a quill and parchment to a Netflix and chill session.
How This Grammar Works
on to mean 'we', you follow two different sets of rules at the same time.on exactly like il (he) or elle (she).est (from être). You never, ever say on sommes. That would be like saying 'we is' in English, but somehow even more painful for a French person to hear.est is singular, the past participle (the part after the auxiliary) decides to be honest about who it's talking about. If on means a group of guys (or a mixed group), you add an s. If on means a group of girls, you add es.on is wearing a mask, but the past participle is the one who reveals the truth. Why does French do this? Because French loves consistency, even when it’s being inconsistent.est as the driver of the car (singular) and the participle as the passengers in the back (plural).s, it’s not the end of the world, but it’s like forgetting the salt in a baguette. It still looks like bread, but something feels slightly off.Formation Pattern
on. Don’t overthink it. Just on. It’s short, sweet, and doesn't require any fancy accents.
est. Remember, this only applies to verbs that use être in the past (like verbs of movement or reflexive verbs). For verbs that use avoir, like manger, there is usually no agreement, so you get a free pass there!
s. Example: On est arrivés le.
es. Example: On est arrivées la.
nous.
On est sortis | We went out
On est sorties | We went out (girls only)
Nous sommes sortis | We went out
Nous sommes sorties | We went out (girls only)
nous) and a late-night kebab shop (on). Both get you fed, but one is much more relaxed. Just remember: on = est + plural ending. If you find yourself writing on sommes, stop, put down the phone, and take a deep breath. We’ve all been there, but we can’t let the intrusive thoughts win.
When To Use It
On est enfin arrivés à Paris ! (We finally arrived in Paris!). Use it when you’re ordering food with a friend: On s'est décidés pour la pizza. (We decided on the pizza). It’s perfect for casual storytelling.nous. on is for the streets, nous is for the office.On a mangé stays mangé no matter how many people are at the table.Common Mistakes
on and nous logic. People often write On sommes partis. C’est une catastrophe ! You have to pick a lane. Either you go full formal with Nous sommes or full casual with On est. Another big one is forgetting the s altogether. Because you hear on est parti and on est partis exactly the same way (the s is silent), it’s incredibly easy to forget to write it. It’s like the ghost of grammar past—it’s there, but you can’t see it or hear it. For English speakers, the concept of 'silent plural markers' is basically a prank played by the French language. Another mistake is over-applying the rule to avoir verbs. You might be tempted to write On a mangés because there were five of you eating tacos. Resist the urge! The agreement is a VIP club, and avoir usually isn't on the list. Finally, watch out for the gender. If you’re a girl out with your female friends, you must use es. Writing On est allés when it’s a girls' trip is like wearing a 'Boy Scout' uniform to a 'Girl Scout' meeting. It’s just not the right fit.Contrast With Similar Patterns
Onvs.Nous:Nousis the 'Golden Retriever' of grammar. It’s reliable, friendly, and everyone understands it, but it’s a bit basic and formal.Onis the 'Cool Cat'. It’s sleek, efficient, and slightly mysterious. Usenousfor essays; useonfor everything else.On(We) vs.On(Generic/Someone): Sometimesondoesn't mean 'we'. Sometimes it means 'one' (as in, 'one should always brush their teeth') or 'someone' (as in, 'someone knocked at the door'). In these cases, you never agree. You leave the participle in its basic masculine singular form. For example:On est allé sur la Lune en 1969(One/Man went to the moon). Here, it’s a general statement about humanity, not a specific group of friends, so nos. How do you know the difference? Context is king. If you’re talking to your friend about your shared plans, it’s 'we'. If you’re reading a philosophical book about the human condition, it’s 'one'.- Auxiliary
êtrevs.avoir: This is the biggest hurdle for A1 learners. Only verbs that useêtre(the 'house of être' verbs like aller, venir, partir, rester) or reflexive verbs (se lever, se doucher) get the plural agreement withon. If you seeon a, leave it alone. If you seeon est, get yoursready.
Quick FAQ
Does on always need an s in the past?
Only if it means 'we' and you're using an être verb. If it means 'someone' or you're using an avoir verb, keep it singular!
Can I use on with my teacher?
It depends on how cool your teacher is. In a formal oral exam, use nous. In a casual classroom chat, on is usually fine.
Why is the s silent? Why do we even write it?
Because the French language loves to make us suffer. Just kidding! It’s to keep the written grammar consistent with the meaning.
What if I don't know the gender of the group?
In French, masculine is the 'default'. If there is at least one guy in a group of 100 people, use the masculine plural s.
Is it on est parti or on est partis in a text?
If you're texting a friend about your shared trip, definitely add the s. Your auto-correct might even help you out if it's feeling generous.
Is this rule new?
The agreement with on = nous was debated for a long time, but it’s now the standard way to write modern, informal French. Even the big dictionaries agree now!
