The Key Things to Know about the French “Savoir” Conjugation

The return of ABBA has got us all singing “knowing me, knowing you, a-ha”, but do you really know the ins and outs of the French savoir conjugation? Savoir, of course, means “to know”, and if you want to add a little “je ne sais quoi” to your French skills, then it’s a verb that you’re going to find very useful.

When to Use the “Savoir” Conjugation

For facts or in-depth knowledge

Often followed by a subordinate clause introduced by a subordinating conjunction such as que, qui, où, and quand, among others. This shows you have knowledge of something.

  • On sait qu’il y a plus de 100 milliards d’étoiles dans la Voie Lactée – We know that there are over 100 billion stars in the Milky Way

For skills

Followed by an infinitive verb, it means “to know how to do something”, and is usually translated by “can”.

  • Je sais danser mais je ne sais pas chanter – I can dance but I can’t sing

For received information

Also introduced by subordinate propositions, this can be used to express something you’ve learned, found out, been told or heard.

  • Je sais que tu démissionnes, je l’ai entendu au réfectoire – I know you’re quitting (your job), I overheard in the canteen

Savoir is one of many verbs ending in -oir. Once you’ve learned the endings for these verbs it will be much easier for you to use all of the other oir verbs.

Connaître vs. Savoir

There are two verbs in French that mean “to know” depending on the context. As we saw above, savoir is used for facts and figures, received information and skills, so when do we use connaître? Connaître is used to talk about the existence of something, things you’ve already experienced before, as well as for talking about places and people you know. You could also remember it as the way of saying what you’re familiar with.

Unlike savoir, connaître is never followed by a verb. Moreover, it can never be followed by a subordinate proposition introduced by que/qui/où/quand/pourquoi etc. Instead, connaître must be used with a direct object, which may be a person, place, or thing.

  • Je pense qu’il connaît ma mere de l’école – I think he knows my mother from school
  • Je connais cette chanson, elle est trop bien ! – I know this song, it’s so good!
  • Nous connaissons ce logiciel, nous l’utilisons au travail – We know this software, we use it at work
  • Ils connaissent Paris, ils y sont allés 3 fois – They know Paris, they’ve been there 3 times

The French imperfect tense can usually be translated with “used to”. It makes it easy to understand and to remember. Unfortunately, with the “savoir” conjugation it’s not quite so straightforward. The imperfect tense is in fact used more frequently than le passé composé with this verb. It is used to express that you knew something in the past, or you already knew something prior to the present moment, as is the case for exclamations as you can see in the first example…

  • Je le savais ! – I knew it!

  • Il savait qu’elle était militaire mais il ne savait pas qu’elle était pilote – He knew she was in the military, but he didn’t know she was a pilot

You’re probably used to using le passé composé to talk about the past tense, yet with the verb savoir the meaning is sometimes slightly different. This tense is often used to talk about when you came to know something, or when you “found out”.

  • Je l’ai su hier lors de la réunion – I found out yesterday during the meeting

  • Elle a su la date depuis 3 semaines, elle devrait être prête – She has known the date for 3 weeks, she should be ready

Expressions with Savoir

There are some expressions that the English language has borrowed from French, meaning that you might already be familiar with them, and some which just might surprise you.

The first three all use two verbs in the infinitive form, the first being savoir.

  1. Savoir-faire – Know-how

Literal translation: To know to do

  • Il faut un certain savoir-faire pour faire ce métier – It requires a certain know-how to do this job

  1. Savoir-vivre – Good manners/etiquette

Literal translation: To know to live

  • Ils sont impolis, ils n’ont aucun savoir-vivre – They’re rude, they have no manners at all

  1. Savoir-être – Social skills

Literal translation: To know to be

  • Elle aime être seule, elle n’a pas de savoir-être – She like being alone, she has no social skills

  1. Je-ne-sais-quoi – a touch/hint of something

Literal translation: I don’t know what

While this is used in English for an indefinable quality, that’s not the case in French. It’s commonly used before an adjective to mean “a small amount of”.

  • Je vois un je-ne-sais-quoi de tristesse dans ses yeux – I can see a hint of sadness in his eyes

  1. Monsieur/Madame je-sais-tout – Know-it-all

Literal translation: Mr/Mrs I-know-everything

  1. Je n’en sais rien – I don’t know anything about it

Literal translation: I know nothing of it

This can be used in a similar way to “I don’t know” but it is a little more powerful.

  • “Où est-ce qu’elle est allée ? Et avec qui ?” – “Where has she gone. And who with?”

“Je n’en sais rien !” – “I don’t know anything about it!”

  1. Ne rien savoir faire de ses dix doigts – To be completely useless, to not know one’s a** from one’s elbow

Literal translation: To not know how to do anything with his ten fingers
