The verb SAVOIR usually means to know and it has irregular forms but it is at least conjugated with avoir in its past tense forms so that makes it easier to learn.  There are, though, two verbs which mean ‘to know’, the other one being connaître. Don’t confuse them: SAVOIR means to know facts, how to do something, and being aware of something, whereas connaître means to know a person (or a place). If you’ve studied Spanish, the rule is similar to ‘saber’ and ‘conocer’.

Uses of SAVOIR

SAVOIR is another irregular verb, meaning it doesn’t follow a recognised pattern when you conjugate it. Make sure you look out for the irregularities in the different tenses and moods but see if you can start to see similarities in the structure of different tenses.

SAVOIR is used in three particular ways.

  1. 1
    SAVOIR means ‘to know’ in the sense of something you have learned or found out. Example: Je sais danser (I know how to dance) and Il sait mon adresse (He knows my address).
  2. 2
    It can be used in the passé composé to express that you have found something out. Example: Ah oui, je l’ai su hier (Oh yes, I found that out yesterday).
  3. 3
    In the conditionnel, it is used to express a sense of ‘could’ or ‘would’ and being able to do something. Example: Je saurais cacher mon colère.  (I would be able to hide my anger).

Conjugation of SAVOIR

Once again, this is an irregular verb and doesn’t follow any of the regular patterns. Keep repeating the verb and listening to the audio, though, and you’ll learn it in no time, but remember that often, different spellings can sound the same in French, so it’s important you secure the spellings as well as the sounds of the words.

Let’s review the conjugation of SAVOIR in the indicative mood.

How to conjugate SAVOIR in the present tense (Présent)

In English, there are two present tenses - the Present Simple and the Present Continuous. In French, there’s only one tense - Le Présent. French is easy, right? 

This particular verb is rarely found in the present continuous - ‘I am knowing’ just doesn’t sound right, does it? - so you only have the present simple meaning in the table below.

Je saisI know
Tu saisYou know
Il / elle saitHe / she knows
Nous savonsWe know
Vous savezYou know
Ils / elles saventThey know

How to conjugate SAVOIR in the Imparfait

The imperfect is used to create a sense of something that continued happening in the past. In English we would say ‘I was doing something’ or that ‘I used to do it’. 

However, with SAVOIR, that sense of continuation is understood without the word ‘was’ being used. 

Before deciding which tense to use (imparfait or passé composé), consider the frequency and how far back in time the events or facts happened.

How to conjugate SAVOIR in the Passé Composé

J’ai suI knew

SAVOIR is another useful but irregular verb to learn. It’s important that you know what it is you know so as not to mix it up with connaître. You might by now be starting to recognise the different patterns that the different tenses bring, and that usually only parts of each form will actually change. Understand the pattern and then think about how the verb you’re learning modifies what you know.

So how will you go about learning them? If you thought learning verbs meant learning by rote and chanting your way through them, you’re mistaken. You can easily and naturally get them set in your memory if you use the audio drills every day.
