Verbs that end in -cer, like lancer, have a spelling change before endings that begin with the hard vowels a or o. Because c followed by a or o would make a hard c sound (like in cold), the c has to change to ç (c with a cedilla) to keep the c soft (as in cell).

In the present tense and the imperative, this c > ç spelling change is found only in the nous conjugation: lançons. It is needed in the present participle, lançant, but not the past participle, lancé.

And it occurs in the following tenses/moods:

There is no spelling change in the conditional, future, or subjunctive.
