解説 un œil in your Level:
At the A1 level, 'un œil' is one of the first body parts you learn. You use it in very simple sentences to describe yourself or others. You learn that you have two eyes ('J'ai deux yeux') and you learn the colors: 'Il a un œil bleu et un œil vert' (though usually, we use the plural). The main challenge at this level is simply remembering that the plural of 'œil' is 'yeux'. You will use it to say things like 'L'œil est petit' or 'Ferme l'œil'. You don't need to worry about complex idioms yet, just the basic physical identification of the organ. You should also learn the word 'lunettes' (glasses) at the same time, as they are used for the eyes. Pronunciation is key: remember the 'n' sound in 'un œil'. Focus on the singular masculine form and the most common plural. This level is about basic survival and description.

At the A2 level, you begin to use 'un œil' in slightly more functional contexts. You might use it to talk about health: 'J'ai mal à l'œil' (My eye hurts) or 'J'ai quelque chose dans l'œil' (I have something in my eye). You also start to encounter the word in very common expressions like 'un coup d'œil' (a quick look). You might say, 'Regarde, j'ai jeté un coup d'œil à ton dessin.' You understand that 'l'œil' is used for seeing and you can describe simple actions like 'Il ouvre un œil'. You are also more comfortable with the irregular plural 'yeux' and can use it in descriptions of people's appearance more fluently. You might learn the parts of the eye like 'les cils' (eyelashes). The focus here is on daily life and basic physical sensations.

At the B1 level, you move beyond the physical and start using 'un œil' in idiomatic and abstract ways. This is the level where you learn 'jeter un œil' (to have a look) and 'avoir l'œil' (to have a good eye for something). You can use 'l'œil' to talk about supervision: 'Garder un œil sur les enfants'. You are expected to understand phrases like 'à l'œil nu' (to the naked eye) and 'du coin de l'œil' (out of the corner of the eye). You can participate in conversations about art or fashion where you might say 'Cet objet tape dans l'œil'. You also begin to distinguish between 'l'œil' (the organ) and 'le regard' (the gaze). Your grammar should be solid, including the correct liaison in 'un œil' and 'des yeux'. This is the level of 'functional idiomaticity'.
At the B2 level, you should be comfortable with a wide range of idioms and nuances. You understand 'coûter les yeux de la tête' (to cost an arm and a leg) and 'entre quatre yeux' (in private/face to face). You can use 'l'œil' in professional or academic contexts, such as 'porter un œil critique sur un texte' (to take a critical look at a text). You understand the social implications of 'faire de l'œil' and the architectural meaning of 'œil-de-boeuf'. You can follow a discussion about surveillance ('l'œil de la caméra') or medical procedures involving the eye. You are aware of the register: 'l'œil' is neutral, while 'les mirettes' is informal. You can describe complex visual scenes using 'au premier coup d'œil' and 'à vue d'œil'. Your use of the word is versatile and integrated into your overall fluency.

Your vocabulary includes derivatives like 'œillade' (a glance/look) and 'œillère' (blinker). You can switch between formal and informal registers with ease, knowing exactly when to use 'l'œil' and when to use a more evocative term like 'le regard'.

At the C2 level, you have a near-native grasp of all the historical, literary, and idiomatic layers of 'un œil'. You can analyze the etymology (from Latin 'oculus') and how it influenced French culture. You are comfortable with the most obscure idioms and can even play with the word in puns or creative writing.

You are perfectly fluent in using the word in every possible context, from the most mundane to the most abstract and poetic.

un œil 30秒で

  • Un œil is the French word for 'an eye'. It is masculine and has a very irregular plural form: des yeux.
  • The word is used both literally for the anatomy and metaphorically for attention, flirting, and supervision.
  • Common idioms include 'jeter un œil' (to have a look) and 'coûter les yeux de la tête' (to be very expensive).
  • Pronunciation involves a mandatory liaison in 'un œil' (/œ̃.nœj/) and 'des yeux' (/de.zjø/).

The French term un œil refers to the biological organ of sight, the eye. While it is a fundamental anatomical term, its usage in French is significantly more complex than its English counterpart due to its highly irregular plural form and its pervasive presence in metaphorical language. In a literal sense, it describes the physical globe located within the orbit of the skull, responsible for photoreception. However, when you move beyond the physical, un œil becomes a vessel for perception, judgment, and social interaction. You will hear it in medical clinics, art galleries, and casual street conversations alike.

Anatomical Context
Used to describe the physical eye, its parts (the iris, the pupil), and its health. Example: 'L'œil gauche est irrité.'
Metaphorical Context
Refers to a person's perspective, attention, or ability to notice details. Example: 'Avoir l'œil pour le détail.'

Le photographe a fermé un œil pour mieux cadrer son sujet.

One of the most striking aspects for English speakers is the transition from the singular œil to the plural yeux. This radical change is a remnant of Old French evolution from the Latin oculus. When using the word, one must be careful with the liaison; 'un œil' is pronounced with a strong /n/ sound connecting the article to the noun (/œ̃.nœj/). It is also essential to note that un œil is masculine. Whether you are talking about the 'eye of a storm' (l'œil du cyclone) or the 'eye of a needle' (le chas d'une aiguille, though sometimes l'œil is used poetically), the word carries a weight of observation.

Il a jeté un œil par la fenêtre pour voir s'il pleuvait.

Furthermore, the concept of 'l'œil' extends into the culinary world (the 'eye' of a piece of meat) and the architectural world (an 'œil-de-boeuf' window). It is a word that bridges the gap between the purely biological and the highly aesthetic. In social settings, 'faire de l'œil' (to make an eye) means to ogle or flirt with someone using just a look. This versatility makes it one of the most important nouns to master at the B1 level, as it begins to unlock the idiomatic richness of the French language. You aren't just seeing; you are engaging with the world through a specific lens.

Using un œil correctly requires an understanding of its grammatical peculiarities. Because it starts with a vowel sound, the definite article becomes l'œil. In the indefinite form, un œil, the liaison is mandatory. When describing someone's eyes, you will almost always switch to the plural les yeux, but when focusing on a single attribute or a specific action involving one eye, the singular is required. For example, if someone has a black eye, you say un œil au beurre noir.

With Adjectives
Adjectives usually follow the noun. 'Un œil attentif' (an attentive eye). Note that the adjective remains masculine.
In Prepositional Phrases
'Du coin de l'œil' (out of the corner of the eye) is a common phrase for peripheral vision.

Elle me surveillait du coin de l'œil pendant que je cuisinais.

Common verbs that pair with un œil include ouvrir (to open), fermer (to close), cligner (to blink/wink - though usually 'cligner de l'œil'), and jeter (to throw/cast). 'Jeter un œil sur quelque chose' is the standard way to say 'to look over something' or 'to check something'. It is less formal than 'examiner' but more active than just 'voir'. In professional contexts, 'avoir un œil sur' means to supervise or keep a watch on a project or a person.

L'expert a posé un œil critique sur le manuscrit.

In more advanced usage, l'œil can represent the person themselves, especially in surveillance. 'L'œil de Moscou' was a term used for Soviet surveillance, and today 'l'œil de la caméra' is common in discussions about media and security. When you want to emphasize that someone is watching very closely, you say they are 'tout œil' (all eye), though 'tout ouïe' (all ears) is more common for listening. Mastering these sentence structures allows a B1 learner to describe physical sensations, professional oversight, and casual observations with native-like precision.

You will encounter un œil in almost every facet of French life. In the morning, you might hear a parent telling a child to 'ouvrir l'œil' (keep your eyes open/stay alert) as they walk to school. In a bakery, you might see a 'pain à l'œil', which is a playful way of describing a certain shape of bread. In the workplace, a manager might ask you to 'garder un œil' on a new intern. The word is ubiquitous because it is the primary sensory organ through which we interpret the world.

In the Media
News reports often use 'sous l'œil de' to mean 'under the watchful eye of' or 'in the presence of'.
In Art and Design
'Trompe-l'œil' is a world-famous French term for art that deceives the eye into seeing three dimensions.

Cette peinture en trompe-l'œil est incroyablement réaliste.

At the doctor's office, specifically the ophthalmologist (l'ophtalmologue), you will hear technical phrases like 'tension dans l'œil' or 'examen de l'œil'. In sports, especially soccer or tennis, commentators often talk about a player having a 'bon œil' to anticipate the ball's trajectory. If you are shopping for clothes, a friend might say a bright color 'pique l'œil' (stings the eye/is very flashy) or that a certain style 'tape dans l'œil' (hits the eye/is very attractive).

Cette robe lui a tout de suite tapé dans l'œil.

In literature and cinema, l'œil is a powerful symbol. From the silent film 'Un Chien Andalou' with its famous (and disturbing) eye scene to the 'œil de verre' (glass eye) of a villain in a novel, the word carries dramatic weight. Even in modern tech, we talk about the 'œil' of a camera lens. Whether you are reading a menu, a medical report, or a fashion blog, the word œil will appear, demanding your attention as both a physical object and a metaphorical tool.

The most frequent mistake learners make with un œil is undoubtedly the plural. Because most French nouns simply add an 's', learners often say 'les œils'. This is grammatically incorrect. The plural is les yeux. This suppletion (where a word changes entirely in its plural form) is one of the most famous traps in the French language. You must memorize them as a pair: un œil, deux yeux.

Gender Confusion
Learners sometimes think it's feminine because it ends in a soft sound. It is masculine: 'le bel œil' (not 'la belle œil').
Liaison Errors
Forgetting to pronounce the 'n' in 'un œil' (/œ̃.nœj/) or the 'z' sound in 'des yeux' (/de.zjø/).

Incorrect: J'ai mal aux œils. Correct: J'ai mal aux yeux.

Another mistake involves the expression 'à l'œil'. In English, 'to the eye' might mean 'visually'. In French, 'à l'œil' is a slang expression meaning 'for free' (e.g., 'manger à l'œil'). If you want to say 'to the naked eye', you must say 'à l'œil nu'. Using 'à l'œil' when you mean 'visually' will lead to confusion, as the listener might think you are talking about getting something without paying.

On ne peut pas voir les bactéries à l'œil nu.

Finally, learners often confuse 'regard' and 'œil'. While 'œil' is the organ, 'regard' is the act of looking or the expression in the eyes. If you want to say 'He has a kind look in his eyes', you should use 'Il a un regard doux', not 'Il a un œil doux' (which would imply one of his physical eyes is soft). Understanding this distinction between the physical organ and the abstract gaze is key to reaching B2 and C1 levels of fluency.

While un œil is the most direct word for 'eye', several synonyms and related terms can add nuance to your French. Depending on whether you are being poetic, medical, or informal, you might choose a different word. For instance, in literature, you might see la prunelle (the pupil), often used in the phrase 'la prunelle de mes yeux' (the apple of my eye).

Le Regard
Focuses on the action of looking. 'Un regard perçant' (a piercing gaze).
La Vue
Refers to the sense of sight itself. 'Perdre la vue' (to lose one's sight).
Les Mirettes
Informal/slang term for eyes. 'Ouvre tes mirettes !' (Open your peepers!).

Il tient à elle comme à la prunelle de ses yeux.

In a technical or medical context, you might refer to the globe oculaire (eyeball). In photography, the 'lens' is called l'objectif, but the 'viewfinder' is sometimes referred to as the viseur. If you want to describe a 'wink', use un clin d'œil. If you want to describe a 'glance', un coup d'œil is perfect. These variations allow you to avoid repeating 'œil' too often in a narrative.

Donne-moi un coup d'œil sur ce document.

Comparatively, 'l'œil' is the neutral, all-purpose term. 'Le regard' is more emotional or expressive. 'La vue' is physiological. 'Les mirettes' is playful. When writing, choosing between 'l'œil' and 'le regard' is often the difference between describing a person's anatomy and describing their soul. For instance, 'Ses yeux étaient bleus' (Anatomy) versus 'Son regard était froid' (Personality/Emotion). Mastery of these synonyms is a hallmark of an advanced learner.

豆知識

The plural 'yeux' comes from the Old French 'oilz'. Over time, the 'l' vocalized and the pronunciation shifted so much that it became a completely different word from the singular.
