-é, -er or -ez

The endings -é, -er and -ez sound the same. Swap the verb for vendre or vendu: if vendre fits, write -er, the infinitive; if vendu fits, write -é, the past participle.

Use -ez only with vous. After a preposition such as pour, de or à, and after a verb like aller, pouvoir or vouloir, write the infinitive.

When two verbs follow each other, the second is usually an infinitive: j'aime danser, il faut travailler. The exception is after avoir or être, where it is the past participle: j'ai dansé, il est tombé.
