Age in French – A Complete Guide 👶🧓🏻

Author: Camille Chevalier-Karfis

Expressing Age in French is tricky both grammatically and vocabulary wise: I’ll explain the differences between “grandir” and “vieillir”, the different life stages, the tricky French adjectives for old and young, how to ask someone’s age in French, and the difference between “an” and “année”.

How to say your age in French?

First of all, there is a big grammatical trap. In English, to talk about how old someone or something is, you use the construction: “to be + number”.

  • He is 5.
    No need to say you’re counting years.

In French, we don’t use the verb to be (“être” in French). We use the construction “to have (so “avoir”) + number + whatever you are counting”

  1. Il a cinq ans – He/it is five (years old)
  2. Il a cinq jours – He/it is five days old.
  3. Il a cinq semaines –  He/it is five weeks old.
  4. Il a cinq mois – He/it is five months old.

We always specify whatever it is that we are counting, even when it’s years.
You cannot say in French “il a cinq”. You would always say “il a cinq ans”.

How To Say “How Old Are You” in French?

To ask someone’s age, you would say:

  1. Quel âge avez-vous ? How old are you, using vous.
  2. Tu as quel âge ? How old are you, using tu and a street French colloquial question form.
  3. Quel âge a-t-il ? How old is he (formal way of asking)
  4. Elle a quel âge ? How old is she (casual street French way)

Asking A Woman Her Age in French – A Big Faux-Pas

Asking a woman her age is considered quite impolite in French, especially if you are a man. If you are curious and still want to know, be delicate about it: “est-ce que je peux me permettre de te demander ton âge ?” – this translates literally into “may I allow myself to ask for your age” but it would be the polite way to ask a woman her age in French.

How To Say “How Many + Age Notion” in French?

If you wanted to ask precisely how many week, months… someone or something was, you would say:

  1. Combien de semaines a le bébé d’Anne ? How many weeks is Anne’s baby (watch out, remember to use “avoir”, not the verb to be in French: “être”)
  2. Ce fromage a été affiné pendant combien de mois ? How many months was this cheese aged?

Learn more about question making with my downloadable French audio lesson (formal way, street way, complex interrogative expression such as “depuis combien de temps” (for how long) etc… asking question is more complex in French than you think, and will unlock your conversation skills).

How To Say Year in French – An versus Année

This is tricky for French students.

“Un an” (masculine, strong liaison with the N making it sound like “un Nan”) and “une année” both translate as “a year”. But they are not interchangeable.

Books will tell you “une année” is a year span, it’s about the duration. I don’t think it’s clear, so I’ll tell you something else, that works most of the time :-)

With a number (except one) use “an” for year.

  • Il a trois ans – he is three.
  • Tous les deux ans – every 2 years.
  • J’y suis allée il y a cinq ans – I went there 5 years ago.

“Année” is mostly used in expressions that you need to learn by heart

  • L’année dernière – last year
  • L’année prochaine – next year
  • Toute l’année – All year long ≠ tous les ans – each year
  • Les années quatre-vingts – the eighties
  • L’année scolaire – the school year
  • L’année d’avant / d’après – the year before / the following year

Memorize these expressions, and this won’t be a problem for you any longer.

How To Say Getting Older in French?

We use specific verbs to say to get older in French:

  1. Les enfants grandissent (grandir) – to grow up. – children grow up.
  2. Les adultes vieillissent (vieillir) – to grow old. – adults grow old.

Both can also “rajeunir” – to become/look younger.

How To Say Old in French?

The French adjective for ‘old’ is “vieux (m), vieille/s (f), or vieil”… which I’ll explain below.

Now, even the French adjective for old is problematic. It’s very irregular.

The French adjective “old” goes BEFORE the noun, when most French adjectives go after the noun.

  1. Vieux + masculine noun, singular and plural (the x is silent)
    un vieux chien, deux vieux chiens – an old dog, 2 old dogs
  2. Vieille + feminine noun (add an S to make it plural)
    une vieille chienne, deux vieilles chiennes – an old female dog, 2 old female dogs
  3. Vieil + masculine noun starting with a vowel or a silent h = the mutant form!
    un vieil immeuble  – an old building
    un vieil ordinateur – an old computer
    Watch out! “Un vieil ami” means an old (time) friend. Say “un ami qui est vieux” if you want to say “a friend who is old”…
    The pronunciation of “vieil” is the same as the feminine “vieille”.

Be careful that the noun “les vieux” to talk about old-people is pejorative in French. Use instead “les personnes âgées” or “les séniors”.

Instead of calling someone “old”, it may be more delicate to call them “not very young” = pas très jeune, or “of some age” = d’un certain âge.

  • Anne est une femme d’un certain âge. Elle n’est plus très jeune mais elle est restée très jeune d’esprit
    Ann is a mature woman. She is no longer young, but she remained young at heart (notice we say “young in spirits”in French)
4 generations: my husband Olivier, our daughter Leyla, Olivier's mom Cristine and grandmother Geneviève ❤️

4 generations French family: my husband Olivier, our daughter Leyla, Olivier’s mom Cristine and grandmother Geneviève ❤️

How to say Young in French?

The French adjective for “young” is also irregular, since it too goes before the noun, but at least it has only one form:

  • Jeune + masculine or feminine noun. Add an S to make it plural.
    Un jeune chien – a young dog
    Trois jeunes chiennes – three young female dogs.

Here also, you’ll use into expressions. “Un jeune-homme” is a young man, so he is young for sure, but it’s also an old fashion greeting : “bonjour jeune-homme”…

Same goes for “une jeune-femme”.

Note, in France we talk about “le premier âge” for infancy, and then “le troisième âge” is for retired but physically active people, and we now talk about “le quatrième âge” for people who are old and ill. But we never talk about “le deuxième âge”…

Can You Understand Today’s Spoken French?

It’s not just slang. The French everybody speaks in France today is NOT the overly enunciated, extremely formal French usually taught to foreigners.
