What is the active voice and passive voice in French?

In French, as in English, sentences can be expressed in either active voice or passive voice. Here's a brief explanation of each:

Active Voice (Voix active):

In the active voice, the subject of the sentence performs the action expressed by the verb.

Example:
- Le chat mange la souris. (The cat eats the mouse.)

In this sentence, "le chat" (the cat) is the subject performing the action of "manger" (to eat).

Passive Voice (Voix passive):

In the passive voice, the subject of the sentence undergoes the action expressed by the verb. The agent (the one performing the action) may or may not be specified.

Example:
- La souris est mangée par le chat. (The mouse is eaten by the cat.)

In this sentence, "la souris" (the mouse) is the subject undergoing the action of "manger" (to eat), and "par le chat" (by the cat) specifies the agent of the action.

The passive voice in French is formed using the appropriate form of the verb "être" (to be) followed by the past participle of the main verb, and optionally followed by the preposition "par" (by) to indicate the agent.
