par la ressemblance

You’ll usually find this phrase tucked into sentences where someone is being identified, mistaken, or categorized. It often follows verbs like identifier (to identify), tromper (to deceive/mistake), or frapper (to strike/impress). For example, if you say Je l'ai reconnu par la ressemblance avec son père, you’re saying the likeness was your 'tool' for recognition. It’s neutral in tone, so you can use it when discussing a serious court case or just explaining why you bought a knock-off designer bag on a sketchy website. You don’t need to overthink the grammar here; just treat it as a prepositional phrase that explains the cause. It's like adding a 'because' clause without having to use a full sentence. Just don't use it to explain why you ate your roommate's leftovers—unless they looked exactly like your leftovers, of course.

Imagine you are scrolling through TikTok and you see a creator who looks exactly like a famous actor. You might comment, "Il est frappant par la ressemblance avec Timothée Chalamet !" In a more professional setting, a botanist might explain that two different plants are often confused par la ressemblance de leurs fleurs. Or, in the world of online shopping, you might find a 'dupe' for a luxury perfume. You could tell your friend, "J'ai acheté ce parfum par la ressemblance avec le Chanel N°5." It shows up in mystery novels too, when the detective realizes two crimes were committed by the same person par la ressemblance du mode opératoire (by the similarity of the operating method). It’s basically the 'Copy-Paste' explanation of the French language. Even AI image generators work par la ressemblance to existing art styles, though they might not admit it!

Use this phrase when the physical or structural likeness is the most important part of your story. It’s perfect for describing family members who look like clones of each other. It’s also great for scientific or technical descriptions where things are grouped together because they look the same. If you are a fan of 'spot the difference' games, this is your go-to expression for explaining why the two images are so hard to tell apart. Use it when you want to sound observant and logical. It’s also very useful in police procedurals—think of all those witnesses saying they picked the guy out of a lineup par la ressemblance. It adds a layer of 'I'm not just making this up' to your observations. Use it when you want to justify a mistake you made because two things were basically identical twins.

Don't use par la ressemblance if you’re talking about things that are identical. If they are the exact same thing, use parce que c'est le même. Also, avoid using it for things that are similar in *vibe* but not in *look*. For instance, if two people have similar personalities but look totally different, par la ressemblance might confuse people into thinking they are physical twins. In that case, use parce qu'ils ont le même caractère. It’s also not the best fit for emotional similarities. If you feel sad because a song reminds you of a breakup, you wouldn't usually say it's par la ressemblance. That’s more of an emotional 'rappel' (recall). And please, don't use it to explain why you're late to work—unless your boss looks like a clock and you got confused.

(Use par, not pour. Par shows the means or the way you recognized him.)

(Par la ressemblance needs to explain an action or a state, it can't just be the whole predicate on its own.)

(You need the word 'avec' to show *what* it resembles.)

A common mistake is forgetting the 'la'. It's not par ressemblance, it's almost always par la ressemblance. Skipping the article makes it sound like you're reading a dry legal textbook from 1845, which is probably not the vibe you're going for at a brunch.

If you want to switch things up, you can use en raison de la similitude. This is slightly more formal and sounds like something a scientist or a lawyer would say. Another option is à cause de la ressemblance, which is very common in spoken French and sounds totally natural. If you want to be poetic, you could try par mimétisme, which implies that something is actively trying to look like something else (like a chameleon). If you’re talking about two things being like 'two peas in a pod', you might say comme deux gouttes d'eau. But par la ressemblance remains the most direct way to say 'because they look alike.' It's the 'plain t-shirt' of French expressions: it goes with everything and never goes out of style.

Sometimes you'll hear par leur ressemblance (by their resemblance) or par une forte ressemblance (by a strong resemblance). You might also see frappé par la ressemblance, which means you were really taken aback by how much two things look alike. Another variation is trompé par la ressemblance, which is what you say when you accidentally kiss a stranger's dog thinking it was yours. (We've all been there, right? No? Just me?). You can also use identifié par la ressemblance, which sounds very CSI-esque. Occasionally, people might say uni par la ressemblance when talking about a group of people who look like they belong together. These variations just add a little spice to the core phrase without changing its DNA.

Is this phrase formal? Not really, it's pretty neutral. You can use it with your boss or your best friend. Can I use it for smells? Usually no. Ressemblance is almost always visual. For smells, you'd use par l'odeur. Is it common in French? Yes, it’s a very standard way to explain why you made a comparison. Do I need to use 'avec' after it? Most of the time, yes, if you are comparing it to something specific. For example, par la ressemblance avec sa sœur. If the context is already clear, you can leave it out. Is there a slang version? Not really, but you might just say 'Ils sont pareils' in casual speech. Can it be used for architecture? Absolutely, you can say two buildings are related par la ressemblance de leur style.
