Si vs. ci

Si and ci are pronounced in the same way, but express completely different meanings. Now's your chance to know how to tell the difference between the two:

We use si:

To express a proposition or condition:

Si j’avais du temps, je partirais en vacances.
If I had the time, I would go on vacation.

Et si on allait au resto ce soir ?
What if we ate out this evening?

To form an indirect question:

Je me demande si Victor viendra.
I'm asking myself if Victor will come.

To contradict a negation, saying 'yes' when someone says 'no':

- Tu ne viens pas ? -Aren't you coming?
- Si ! Attendez-moi ! -Yes! Wait for me!

To add a degree of intensity:

Ce Victor, il est si gentil ! (= tant)
This Victor, he is so kind!

Muriel est si petite qu’elle passe sous la table.
Muriel is so small she can pass under the table.

We use ci:

To stress a demonstrative adjective (as opposed to ):

Ce livre-ci est beaucoup plus intéressant que celui-là.
This book is much more interesting than that one.

Lequel tu préfères ? Celui-ci ou celui-là ?
Which do you prefer? This one or that one?

With an adjective or adverb:
Ci-joint mon CV.
My CV is attached.
