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: Imperfect - singular conjugations plus the third person pluralPassé simple - all conjugations except the third person pluralImperfect subjunctive - all conjugations There is no spelling change in the conditional, future, or subjunctive.The table below summarizes just the spelling change conjugations, or you can see lancer conjugated in all tenses.All verbs that end in -cer undergo this spelling change, including annoncer to announce avancer to advance commencer to begin dénoncer to denounce divorcer to divorce effacer to erase lancer to throw menacer to threaten placer to put prononcer to pronounce remplacer to replace renoncer to renounce Present Imperfect Passé simple Imperfect subjunctive Participles je lance lançais lançai lançasse tu lances lançais lanças lançasses Present il lance lançait lança lançât lançant nous lançons lancions lançâmes lançassions vous lancez lanciez lançâtes lançassiez Past ils lancent lançaient lancèrent lançassent lancé Continue Reading How to Conjugate French Spelling-Change Verbs -GER - French Spelling Change Verbs Examples How Would You "Announce" a Conjugation of "Annoncer"?
