To make up for the difficulty in knowing when to use the French subjunctive, the conjugations are relatively easy. All regular -er, -ir, and -re verbs as well as many irregular verbs* are conjugated according to this pattern:
Start with the present tense ils conjugation of the verb
Drop –ent to find the subjunctive stem
Add the appropriate subjunctive ending: -e, -es, -e, -ions, -iez, -ent
learn the irregular verbs
