How do you say 'back' in French? You might think there's a single, simple answer, but like many things in language learning, it's a bit more nuanced! The word you use depends entirely on the context. Are you talking about your back, as in the body part? Are you saying you'll be right back? Or are you referring to the back of a room?

Don't worry, we've got your back! In this article, we'll explore nine different ways to say 'back' in French, complete with examples, so you can use each one with confidence.

Let’s dive in and get these useful terms straight!

1. The Standard 'Back' (the body part) – Le Dos

The most common and direct word for the 'back' in French, referring to the part of the human body, is le dos.

Le dos is a masculine noun, so you always use masculine articles and adjectives with it (e.g., le dos, mon dos, un dos musclé). The spelling is the same in both singular and plural forms, so 'the back' is le dos and 'the backs' is les dos.

One of the most essential phrases you'll learn with this word is avoir mal au dos, which means 'to have a backache' or 'to have back pain'. Notice the contraction of à + le to au.

Le dos is central to many idioms. For example, tourner le dos à quelqu'un literally means 'to turn one's back to someone,' but it's used figuratively to mean ignoring, abandoning, or rejecting them.

Another common expression is en avoir plein le dos, which is a colloquial way to say you're 'fed up' or 'have had enough' of something. For example, J'en ai plein le dos de ce bruit ! means 'I'm so sick of this noise!'

💡 * J'ai très mal au dos aujourd'hui.

• Il portait un lourd sac sur le dos.
• Ne me tourne pas le dos quand je te parle !
• Les enfants sont montés sur le dos de leur père.
• J'en ai plein le dos de tes mensonges.

The 'back' or 'rear' of an object or place – l'arrière

When you need to talk about the 'back' or 'rear' of a physical object or space in French, the most common and versatile word you'll use is l'arrière.

L'arrière is a masculine noun that refers to the part of something opposite its front. Unlike le dos, which means 'back' for a person or animal, l'arrière is used for inanimate objects, vehicles, and locations.

This word is extremely common when discussing transportation. You can place your bags à l'arrière de la voiture (in the back of the car) or choose a seat à l'arrière de l'avion (at the rear of the plane).

The usage extends naturally to buildings and properties. For example, la porte de l'arrière is the 'back door', and the stockroom of a shop is often called l'arrière-boutique (the back room).

You'll also frequently see it in the adverbial phrase en arrière, meaning 'backwards'. To 'look back' is regarder en arrière, and to 'move backwards' is aller en arrière.

Essentially, if you're referring to the rear portion of any non-living thing, from a truck to a theater, l'arrière is almost always the correct and natural choice.

💡 * Les toilettes sont à l'arrière du restaurant.

• Ne regarde pas en arrière, continue d'avancer !
• J'ai mis les valises dans le coffre à l'arrière de la voiture.
• L'arrière de la maison donne sur un petit parc.

The 'backside' or 'behind' – le derrière

Le derrière is a very common and polite way to refer to someone's "backside," "bottom," or "behind" in French. It's a neutral term that you can use in almost any situation without causing offense, making it a safe and useful word for learners.

The word derrière on its own is a preposition or adverb meaning "behind." When used as a noun, le derrière, it specifically refers to the buttocks. It is always a masculine noun, so you will always see it preceded by le or un.

Le derrière is the go-to term for polite company and is frequently used when speaking to or about children. It is much less direct than les fesses (buttocks/butt) and infinitely more polite than the vulgar term le cul. Think of it as the direct French equivalent of the English words "bottom" or "behind."

You'll often hear parents use this term with their children. For instance, telling a child to sit down might involve saying, "Assieds-toi sur ton derrière" (Sit on your bottom). It's the standard anatomical term in contexts where you want to be respectful and not overly clinical or informal.

💡 * Le bébé est tombé sur le derrière, mais il n'a pas pleuré.

• Le pantalon de ce petit garçon est sale sur le derrière.
• Assieds-toi sur ton derrière et écoute bien !
• Mon chien se gratte le derrière sur le tapis.

The 'back' of a chair – le dossier

The French word for the back of a chair or seat is le dossier. As a masculine noun, it is always used with masculine articles like le or un when referring to furniture.

Be aware that le dossier has another very common meaning: a 'file,' 'folder,' or 'case file' (a collection of documents). This dual meaning makes context extremely important for understanding.

Discerning the meaning is simple with context. If the conversation is about furniture, cars, or airplanes, le dossier refers to the backrest. If it's about work, administration, or legal matters, it refers to a file.

💡 * Le dossier de cette chaise est très confortable. (The back of this chair is very comfortable.)

• Tu peux incliner le dossier de ton siège. (You can recline the back of your seat.)
• J'ai besoin de ce dossier pour la réunion de demain. (I need that file for tomorrow's meeting.)
• L'avocat a examiné le dossier de son client. (The lawyer reviewed his client's file.)

1. The 'Reverse Side': Le Revers vs. Le Verso

When talking about the 'reverse side' of something in French, you'll encounter two main words: le revers and le verso. While they seem similar, they are not interchangeable and apply to different contexts.

Le verso is used specifically for the back of a flat, written, or printed surface, like a page in a book, a photograph, or a sheet of paper. Its direct opposite is le recto (the front side). Think of the common term recto verso for double-sided printing.

Le revers is more versatile. It refers to the other side of physical objects like a coin, a medal, or a hand. It's also used for the lapel of a jacket (le revers de la veste). Figuratively, it means the 'downside' or 'flip side' of a situation, as in le revers de la médaille (the other side of the coin).

Here’s the simple rule: Use le verso for paper, pages, and documents. Use le revers for most other objects (coins, clothes) and for abstract 'downsides'.

💡 * Veuillez signer au verso de la feuille, s'il vous plaît. (Please sign on the back of the sheet.)

• J'admire le revers de cette vieille pièce de monnaie. (I'm admiring the reverse side of this old coin.)
• La célébrité a son revers, comme le manque d'intimité. (Fame has its downside, such as the lack of privacy.)
• Les instructions sont imprimées au verso de la boîte. (The instructions are printed on the back of the box.)

The adverb for 'backwards' – en arrière

The most direct and common way to say 'backwards' in French, particularly when referring to physical movement, is en arrière.

You'll frequently see en arrière paired with verbs of motion to describe the direction of an action. For example, marcher en arrière means 'to walk backwards,' and faire un pas en arrière means 'to take a step back.' It specifies the direction of the movement.

Beyond physical movement, en arrière is also used to mean 'back' or 'behind' in the context of looking. The phrase regarder en arrière means 'to look back' or 'to look behind you.' This can be used both literally and figuratively, as in looking back on one's past.

It's important not to confuse en arrière with à l'envers. While en arrière means backwards in terms of direction, à l'envers means 'upside down,' 'inside out,' or 'the wrong way around.' For instance, you would wear a shirt à l'envers, but you would walk en arrière.

💡 * Il a fait un bond en arrière pour éviter la voiture. (He jumped backwards to avoid the car.)

• Ne regarde pas en arrière, continue d'avancer. (Don't look back, keep moving forward.)
• Le film passe la scène en arrière pour montrer un indice. (The movie plays the scene backwards to show a clue.)
• C'est difficile de patiner en arrière au début. (It's difficult to skate backwards at first.)

The expression for 'to be back' or 'returned' – être de retour

To express that someone 'is back' or 'has returned,' a very common French expression is être de retour.

Literally translating to 'to be of return,' this phrase is the standard way to state that a person has come back to a location after being away. It's the direct equivalent of saying 'I am back' or 'she has returned' in English.

The structure is straightforward: you simply conjugate the verb être (to be) for the correct subject and tense, and then add the fixed phrase de retour. For example, you would say 'Je suis de retour' for 'I am back' or 'Elle sera de retour demain' for 'She will be back tomorrow.'

💡 * Je suis de retour de vacances. (I am back from vacation.)

• Le patron sera de retour au bureau lundi. (The boss will be back at the office on Monday.)
• Ils sont enfin de retour après un long voyage. (They are finally back after a long trip.)
• À quelle heure penses-tu être de retour ? (What time do you think you will be back?)

The 'backbone' or 'spine' – l'épine dorsale

The French term for 'backbone' or 'spine' is l'épine dorsale. This expression is used in both a literal, anatomical sense and a figurative one, much like its English equivalent.

Literally, l'épine dorsale (feminine noun) refers to the series of vertebrae extending from the skull to the pelvis, forming the main support of the body. You would use this term in a medical or biological context.

Figuratively, l'épine dorsale describes the main support or most important part of a system, organization, or concept. It's the fundamental element that gives structure and strength to the whole.

This phrase is common in more formal or professional discussions. For example, you might talk about the 'backbone of the economy' (l'épine dorsale de l'économie) or the 'backbone of a project' (l'épine dorsale d'un projet).

💡 * Le patient souffre d'une douleur à l'épine dorsale. (The patient is suffering from a pain in the spine.)

• La confiance est l'épine dorsale de toute relation saine. (Trust is the backbone of any healthy relationship.)
• Les bénévoles sont la véritable épine dorsale de notre association. (The volunteers are the true backbone of our organization.)
• Ce chapitre constitue l'épine dorsale du livre. (This chapter constitutes the backbone of the book.)

The 'background' (in a picture or scene) – l'arrière-plan

The most direct and common way to say 'the background' in a visual context like a picture, painting, or scene is l'arrière-plan (masculine). It specifically refers to the part of a scene that is furthest from the viewer.

This is a compound noun formed from two words: arrière, meaning 'back' or 'behind,' and plan, meaning 'plane' or 'level.' Together, they literally mean 'the back plane,' which is a perfect description of its role in visual composition.

Use l'arrière-plan to describe the scenery or objects behind the main subject. It is the direct opposite of le premier plan, which means 'the foreground.' Thinking in terms of these two opposites helps solidify its meaning.

You might also encounter the word le fond, which can also mean 'background.' While sometimes interchangeable, l'arrière-plan is more specific to visual layers in art or photography. Le fond is more general and can refer to a background color (la couleur de fond) or background noise (le bruit de fond).

💡 * On voit des montagnes à l'arrière-plan de la photo. (We see mountains in the background of the photo.)

• Le peintre a utilisé des couleurs sombres pour l'arrière-plan. (The painter used dark colors for the background.)
• L'action principale se déroule au premier plan, avec des figurants à l'arrière-plan. (The main action takes place in the foreground, with extras in the background.)
• La personne à l'arrière-plan est floue. (The person in the background is blurry.)
