Cedilla
In French, cedilla is only used under letter c in from of voyels a, o et u. It is used to transform sound k into s. It systematically appears on some conjugation in order to have the s sound.
- je plaçais
- nous glaçons
- j'ai reçu
On the other hand, in front of an e or an i, do not put a cedilla because one already has the sound [s].
- il place
- nous placions
- vous glacez
