French Expressions of Age: I have 20 years (avoir ... ans)
avoir plus ans.
Grammar Rule in 30 Seconds
In French, you don't 'be' an age; you 'have' years.
- Use the verb 'avoir' (to have) instead of 'être' (to be).
- Always add the word 'ans' (years) after the number.
- Never translate 'I am 20' literally as 'Je suis 20'.
Overview
In French, expressing age differs fundamentally from English. You do not “be” your age; instead, you “have” your age. This core concept is critical for understanding why the verb avoir (to have) is universally used, rather than être (to be).
The phrase J'ai vingt ans translates literally to "I have twenty years," directly reflecting this possessive construction. This linguistic divergence often presents a challenge for learners, as the English I am 20 years old leads naturally to the incorrect Je suis vingt ans. Mastering this distinction at an early stage establishes a foundational understanding of French expression.
This rule is not an arbitrary grammatical quirk but a reflection of how French conceptualises age. It is viewed as a quantity or possession that one accumulates over time. Every year, you gain an additional unit of age, which you then possess.
This perspective permeates various idiomatic expressions in French, where avoir is used for states or conditions that are temporary or perceived as qualities one holds (e.g., avoir faim – to be hungry, literally "to have hunger"). Therefore, understanding avoir... ans is not merely about stating age, but about grasping a broader pattern of French thought concerning personal attributes and states.
How This Grammar Works
avoir, meaning "to have." This verb is highly irregular and its accurate conjugation is indispensable for correctly stating or asking about age. You cannot progress without memorizing its forms. The structure consistently involves a subject, a conjugated form of avoir, a number, and finally the word ans (years).ans is always used, except in the rare instance of one year, where an is used.I am.... French, however, treats age as a quantity of years one possesses.J'ai trente ans. This directly implies ownership over trente ans (thirty years). This possessive paradigm extends to other physical and emotional states, such as avoir froid (to be cold), avoir chaud (to be hot), avoir soif (to be thirsty), or avoir peur (to be afraid).ans (or an for one year). Omitting ans renders the statement incomplete and grammatically incorrect, akin to saying "I have twenty" in English without specifying "twenty what?" This insistence on ans underscores the quantifiable nature of age in French. The specific conjugation of avoir must match the subject pronoun or noun.nous avons (we have) is used for nous (we), while elle a (she has) corresponds to elle (she).avoir is conjugated, particular attention must be paid to liaisons and contractions. Liaisons occur when a normally silent final consonant of a word is pronounced at the beginning of the next word if that word starts with a vowel or a silent h. For example, nous avons is pronounced nooz-ah-vohn, with the s of nous linking to the a of avons.ils ont becomes eelz-ohn. The contraction j'ai for je ai is mandatory; je ai is never used. This is a common phonetic rule in French to avoid vowel clashes.Word Order Rules
avoir + Number + ans.Je, Tu, Il/Elle |\avoir | The correctly conjugated form of the verb avoir. | ai, as, a |\dix-huit, vingt |\ans | The word for "years." (Use an for one year old). | ans, an |J'ai dix-huit ans. Here, J' is the contracted subject pronoun je, ai is the conjugated avoir for je, dix-huit is the number, and ans is the obligatory noun.s in ans is typically silent, but it participates in a liaison when followed by a vowel sound, such as J'ai vingt-cinq ans et un mois (vin-sin-kan-e-un-mwa). However, in the standard ... ans construction, the s is silent.ans (or an). A statement like J'ai vingt is incomplete. It carries the meaning "I have twenty," which begs the question "twenty what?" While a native speaker might infer ans from context in a casual, highly abbreviated exchange, it is grammatically incorrect and considered a significant error for a learner.ans is immediately followed by a more specific duration, such as J'ai vingt ans et demi (I am twenty and a half years old), where ans precedes et demi. But even here, ans is present.Formation Pattern
avoir conjugations. This section outlines the precise steps to construct these phrases, from identifying the subject to appending the necessary ans.
avoir you need.
Je (I)
Tu (You - informal singular)
Il/Elle/On (He/She/One)
Nous (We)
Vous (You - formal singular or plural)
Ils/Elles (They - masculine/mixed or feminine plural)
avoir: Select the correct form of avoir that corresponds to your chosen subject. Remember that avoir is irregular.
avoir Conjugation | Pronunciation Note |\
Je | ai (J'ai) | Mandatory contraction J'ai. Never Je ai. |\
Tu | as | Tu + as. The s is silent. |\
Il/Elle/On| a | Il a, Elle a, On a. The a is pronounced as in "father." |\
Nous | avons | Liaison: Nous-z-avons. The s of nous links. |\
Vous | avez | Liaison: Vous-z-avez. The s of vous links. |\
Ils/Elles| ont | Liaison: Ils-z-ont. The s of ils links. |
vingt (20), trente-cinq (35), quarante (40). Pay attention to French number pronunciation, especially compound numbers.
ans (or an): Crucially, append ans after the number. If the age is one year old, use un an. For any other age, ans is plural and remains so regardless of the number. For example, J'ai un an (I am one year old) versus J'ai deux ans (I am two years old). The s in ans is generally silent unless it forms a liaison.
My sister is 23 years old.
Ma sœur (which is Elle)
avoir conjugation for Elle: a
vingt-trois
ans
Ma sœur a vingt-trois ans.
When To Use It
Subject + avoir + Number + ans pattern. You use it in any situation where you need to disclose age.- Informal:
J'ai dix-neuf ans.(I am nineteen years old.) - Formal:
Mon collègue a quarante-deux ans.(My colleague is forty-two years old.) - General Statement:
Les enfants ont cinq ans.(The children are five years old.)
tu (informal 'you') and vous (formal singular 'you' or plural 'you').Quel âge as-tu ? | Friends, family, children, peers you address with tu. |\Quel âge avez-vous ? | Strangers, elders, superiors, or a group of people. Use vous for respect. |\Tu as quel âge ? / T'as quel âge ? | Very close friends, texting, informal social media. Note the T'as contraction. |tu with someone you should address with vous can be perceived as disrespectful, especially in professional or initial social encounters. The inverted question forms (Quel âge as-tu ?, Quel âge avez-vous ?) are standard and preferred for a neutral or formal tone.Tu as quel âge ? is common in highly informal settings, and its even more contracted form T'as quel âge ? is typically reserved for written informal communication or very relaxed spoken contexts.Quel âge as-tu/avez-vous ?) can sometimes be considered a personal question in French culture, particularly for adults, and especially for women. It's generally more acceptable in contexts where age is relevant (e.g., for legal purposes, or among young children). In adult social settings, it is often avoided unless a close relationship is established or the context clearly warrants it (e.g., discussing common life stages like retirement or career progression).Si ce n'est pas indiscret, quel âge avez-vous ? (If it's not indiscreet, how old are you?) is advisable.Common Mistakes
- 1The
êtreTrap (Je suis...): This is the most prevalent and fundamental error. Learners instinctively translate "I am 20 years old" directly intoJe suis vingt ans. This is incorrect. In French,être(to be) is used for inherent qualities or identities, whileavoir(to have) is used for quantities or states one possesses.Je suis vingt ansliterally implies "I am the number 20," which is nonsensical. Remember: you have years, you don't are years.
- Incorrect:
Je suis vingt ans. - Correct:
J'ai vingt ans.
- 1Omitting
ans: Another frequent mistake is to leave out the wordans(years) after the number. For example,Il a trente(He has thirty). While a native speaker might understand the impliedansin a very casual, context-rich conversation, it is grammatically incomplete and sounds unnatural. French requires the unit of measurement (ans) to specify what quantity is being possessed.
- Incorrect:
Elle a quarante. - Correct:
Elle a quarante ans.
- 1Incorrect
avoirConjugation: Becauseavoiris an irregular verb, its conjugation can be tricky. Errors often occur withtu asvs.il/elle a, or with the mandatory contractionJ'ai.
- Incorrect:
Tu a vingt ans.(Missingsfortuform) - Correct:
Tu as vingt ans. - Incorrect:
Je ai trente ans.(Missing contraction) - Correct:
J'ai trente ans. - Incorrect:
Ils on trente ans.(Missingtforils/ellesform) - Correct:
Ils ont trente ans.
- 1Confusion with
un anvsun ans: When referring to someone who is one year old, the singularanmust be used. For all other ages, the pluralansis correct. Beginners sometimes incorrectly apply the pluralansto one year.
- Incorrect:
Mon fils a un ans. - Correct:
Mon fils a un an.
- 1Lack of Liaison: While perhaps not a grammatical error that impedes comprehension, omitting liaisons (e.g., pronouncing
nous avonsasnou avoninstead ofnooz-avon) marks a speaker as non-native. At A1, understanding the concept is key, and practicing correct liaisons will improve fluency.
Contrast With Similar Patterns
avoir extends beyond age to several other common states and conditions, which can be both helpful as a pattern and a source of misapplication if not fully understood. It is equally important to differentiate it from descriptions using être.Avoir for Other States/Conditions:avoir for many expressions where English uses to be. These are often temporary physical or emotional states, or quantities. This consistency is a powerful pattern to recognize.Avoir faim | You possess hunger. |\Avoir soif | You possess thirst. |\Avoir froid | You possess the sensation of cold. |\Avoir chaud | You possess the sensation of heat. |\Avoir peur | You possess fear. |\Avoir sommeil | You possess sleepiness. |\Avoir raison | You possess reason/correctness. |\Avoir tort | You possess wrongness/error. |\Avoir de la chance | You possess luck. |avoir des ans (have years), you avoir faim (have hunger). This possessive construction is a hallmark of French for these types of expressions. The key is to remember that these are not things you are, but rather conditions or sensations you hold or experience.Être for Descriptions:avoir is used for age and other possessive states, être (to be) is reserved for inherent qualities, identity, nationality, profession, and permanent characteristics. Confusing the two would lead to fundamental errors in description.Avoir | J'ai trente ans. | I am thirty years old (I have thirty years). |\Être | Je suis français. | I am French. |\Être | Elle est médecin. | She is a doctor. |\Être | Il est grand. | He is tall. |\Être | Nous sommes fatigués. | We are tired. |\Être | Vous êtes marié(e). | You are married. |\être describes who or what someone fundamentally is, whereas avoir describes what someone possesses or how they feel temporarily. This distinction is crucial for building a correct mental framework for French grammar.Real Conversations
Understanding grammatical rules is one aspect of language acquisition; observing and internalizing how these rules function in authentic, contemporary interactions is another. Here, we present various real-world scenarios demonstrating the expression of age in French, from casual exchanges to more formal inquiries, including modern communication styles.
Scenario 1
Camille: Salut, je m'appelle Camille. J'ai dix-neuf ans. Et toi ?
- (Hi, my name is Camille. I'm nineteen. And you?)
Théo: Moi, c'est Théo, j'ai vingt ans. On est dans la même promo ?
- (I'm Théo, I'm twenty. Are we in the same year?)
Camille: Oui, je crois ! Super !
- (Yes, I think so! Great!)
Observation
j'ai is natural in spoken French.Scenario 2
Madame Dubois: Votre fils, il a quel âge maintenant ?
- (Your son, how old is he now?)
Monsieur Martin: Il a sept ans et demi. Il rentre au CE1 l'année prochaine.
- (He's seven and a half. He's going into second grade next year.)
Observation
il a quel âge ? is a common, slightly less formal way to ask than full inversion, especially when talking about a third person. The et demi (and a half) is a natural addition for specifying age.Scenario 3
Recruteur: Pourriez-vous me dire quel âge vous avez ?
- (Could you tell me how old you are?)
Candidate: Oui, bien sûr. J'ai vingt-cinq ans.
- (Yes, of course. I am twenty-five.)
Observation
vous and a polite introductory phrase (Pourriez-vous me dire...). The candidate responds directly, also using the formal J'ai.Scenario 4
Lea: Hey, t'as quel âge déjà ? Pour l'inscription au club.
- (Hey, how old are you again? For the club registration.)
Tom: G 21. Pq ?
- (I'm 21. Why?)
Lea: Ok cool, merci. Faut avoir + de 18 ans.
- (Okay cool, thanks. You need to be over 18.)
Observation
T'as is a contraction of Tu as, and G is a phonetic shorthand for J'ai. This kind of abbreviation is common in quick digital communication but should be avoided in formal contexts.Scenario 5
Âge : (Vingt-huit) 28 ans
Observation
ans.These examples illustrate the flexibility and context-dependence of age expressions in French, from their full, formal construction to highly abbreviated informal forms. Recognizing these variations will significantly enhance your communicative competence.
Quick FAQ
ans when stating age?ans is required. In extremely casual, fast-paced spoken French, where context is absolute, native speakers might occasionally drop ans (e.g., J'ai vingt when pointing to someone celebrating their 20th birthday).ans (or an).an instead of ans?un an (singular an) only when referring to the age of one year old. For any age greater than one (e.g., two years, three years, etc.), you must use the plural form ans. The number un (one) is the only exception.Mon bébé a un an.(My baby is one year old.)Ma nièce a deux ans.(My niece is two years old.)
vingt (twenty) remains vingt whether referring to a boy or a girl, or multiple people. The only exception is the number one, which takes the masculine form un before an (un an).vingtaine (twenties), trentaine (thirties), quarantaine (forties), etc. You say Avoir la vingtaine, Avoir la trentaine, etc. This is a more advanced concept than A1-level age expression, but it's useful to be aware of.J'ai la vingtaine.(I am in my twenties.)Elle a la cinquantaine.(She is in her fifties.)
s in ans?s in ans is generally silent (ahn). However, if ans is immediately followed by a word starting with a vowel sound, a liaison may occur, causing the s to be pronounced as a /z/ sound. For instance, J'ai vingt ans et demi would be pronounced with a liaison, linking ans to et (vint-ahn-z-et-dmi).s in isolation is sufficient.quel âge used for "how old"?Quel is an interrogative adjective meaning "which" or "what." In the context of age, quel âge literally means "what age." This construction is typical in French for asking about quantities or characteristics (quelle couleur ? – what color? quelle heure ? – what time?). It directly asks for the specific age value rather than a general state of being.Conjugation of Avoir (To Have)

Yes, unless you are 1 year old (1 an).
Use 'Quel âge as-tu ?' or 'Quel âge avez-vous ?'.
No, use 'avoir' for objects too (e.g., 'La maison a 50 ans').
The structure is the same, just use 'avez-vous'.
You say 'J'ai un an'.
Only if you are describing something else, not age.
