French Relative Pronouns with Prepositions (auquel, pour qui)
Grammar Rule in 30 Seconds
When a preposition (à, de, pour, avec) precedes a relative pronoun, you must use the 'lequel' series instead of 'qui' or 'que'.
- Use 'lequel' (and variants) after prepositions for things: 'La chaise sur laquelle je suis assis.'
- Use 'qui' after prepositions for people: 'L'ami avec qui je voyage.'
- Use 'lequel' (and variants) after prepositions for people in formal contexts: 'L'homme avec lequel je travaille.'
Overview
Ever felt like your French is stuck in a loop of short, choppy sentences? You know the vibe. "I have a friend.
I work with this friend. We like pizza." It sounds like a first-grade reader, right? If you want to sound like a native (or at least like someone who’s had their coffee), you need the glue of the French language: relative pronouns with prepositions.
These are the tools that let you weave complex thoughts together without sounding like a broken GPS. At the C1 level, you aren't just trying to be understood; you’re trying to be precise, elegant, and maybe a bit sophisticated. These pronouns—think auquel, pour qui, or avec laquelle—are your ticket to the big leagues.
They allow you to refer back to people or things while accounting for the verbs or phrases that require a preposition. It’s like being a linguistic architect. You’re building bridges between ideas instead of just piling bricks on top of each other.
Plus, using them correctly is the ultimate flex in a job interview or a heated group chat debate about which Netflix show is actually worth the hype. Just don't use them to over-explain your cat's dietary needs; some things are better kept simple. Let’s get you sounding more like a Parisian intellectual and less like a phrasebook.
How This Grammar Works
avec, pour, sur, or chez). Second, you have the pronoun that represents the person or thing you're talking about.qui.lequel family. This family is a bit high-maintenance because it changes based on gender and number. You’ve got lequel, laquelle, lesquels, and lesquelles.à or de, they merge with the pronoun to create contractions like auquel or desquels. It’s basically grammar math.Formation Pattern
à, de, pour, avec, sur? For example, penser à (to think about) or travailler pour (to work for).
qui. It’s easy, it’s classic, and it never changes gender.
lequel family. Match it to the noun it replaces.
à: à + lequel = auquel; à + lesquels = auxquels; à + lesquelles = auxquelles. (Note: à laquelle stays separate!).
de: de + lequel = duquel; de + lesquels = desquels; de + lesquelles = desquelles. (Note: de laquelle stays separate!).
lequel family:
lequel (Example: Le projet pour lequel...)
laquelle (Example: La raison pour laquelle...)
lesquels (Example: Les amis avec lesquels...)
lesquelles (Example: Les idées auxquelles...)
When To Use It
- Social Media & Tech: Use them to describe the app
sur laquelle(on which) you spend too much time, or the TikTokerà qui(to whom) you sent a DM. - Professional Settings: Essential for job interviews. You’ll talk about the company
pour laquelleyou worked or the goalsauxquelsyou contributed. It makes you sound organized and serious, even if you’re secretly wearing pajama bottoms under your desk during the Zoom call. - Complex Relationships: When describing people,
quiis your best friend after a preposition.L'ami avec qui je voyage(The friend with whom I travel). While you can uselequelfor people to be extra precise or formal,quiis the standard for everyday life. - Spatial Relationships: Use them with prepositions of place.
La table sous laquelle le chat se cache(The table under which the cat is hiding). - Abstract Concepts: Talk about the values
auxquellesyou are attached.
auquel and company. It’s the difference between saying "The dog. I gave a bone to it" and "The dog to which I gave a bone." One sounds like a caveman; the other sounds like a poet.Common Mistakes
- The "Dont" Overuse: Many learners try to use
dontfor every prepositional phrase involvingde. If the preposition is part of a compound phrase likeà côté deoren face de, you cannot usedont. You must useduquel. - ✗
La banque dont j'habite à côté. - ✓
La banque à côté de laquelle j'habite.(The bank next to which I live). - Forgetting Agreement: Don't use
lequelfor everything. If you're talking aboutla voiture, uselaquelle. It’s a tiny detail, but it’s the hallmark of a high-level speaker. - Misplacing the Preposition: Never put the preposition at the end of the sentence like in English.
- ✗
La fille que je parle à. - ✓
La fille à qui je parle. - The "Qui" for Objects Trap: You cannot use
quifor objects after a preposition. - ✗
Le stylo avec qui j'écris. - ✓
Le stylo avec lequel j'écris.
Qui is for humans (and maybe your very spoiled dog), not for office supplies.- Contraction Failure: Forgetting that
à + lequelbecomesauquel. It’s like saying "I is" in English—people know what you mean, but it hurts their ears just a little bit.
Contrast With Similar Patterns
dontvs.duquel: Usedontwhen the verb simply takesde(likeparler deoravoir besoin de). Useduquelwhen you have a complex preposition (likeà cause de,loin de,le long de). Think ofdontas the shortcut andduquelas the scenic route.quevs.lequel:queis for direct objects (no preposition).lequelis for indirect objects (after a preposition). If there’s apour,avec, orsur,queis out of the game.oùvs.dans lequel: For locations, you can often useoù.La ville où j'habiteis fine. But if you want to be more specific, like "the box inside which I put my keys,"dans laquelleis more precise.Oùis like a broad brush;dans lequelis like a fine-liner pen.qui(alone) vs.celui qui: Don't confuse the relative pronoun with the demonstrative pronoun.L'homme à qui je parle(The man to whom I speak) vs.Celui à qui je parle(The one to whom I speak).
Quick FAQ
Can I use lequel for people?
Yes, but it sounds more formal or is used to avoid ambiguity if there are multiple people mentioned. In casual convo, stick with qui for humans.
Is auquel used for time?
Generally, no. We use où or au moment où. Auquel is more for verbs taking à, like participer à.
What if the preposition is entre or parmi?
For these, you must use the lequel family, even for people. Les amis parmi lesquels je me sens bien (The friends among whom I feel good).
Does this work with penser à?
Absolutely. C'est un problème auquel je pense souvent. (It's a problem I think about often).
Is there a plural for qui?
Nope. Qui stays the same whether you’re talking about one person or a whole crowd. Minimalist vibes!
Can I use dont with à cause de?
No. Dont hates complex prepositions. Use à cause duquel instead. It’s longer, but it’s the only way.
What about chez?
L'ami chez qui je dors. (The friend at whose place I'm sleeping). Simple and effective.
