Understanding “avant de”: The Infinitive Structure
“Avant de” is used when the verb that follows is in its infinitive form. This construction is straightforward and is applied when the subject of both clauses is the same.
When to Use “avant de”
Use “avant de” followed by an infinitive verb when you want to talk about an action that happens before another action carried out by the same person or thing.
- Je me lave les mains avant de manger. (I wash my hands before eating.)
- Il lit un livre avant de dormir. (He reads a book before sleeping.)
Key Points to Remember
- Always use the infinitive form of the verb after “avant de.”
- No change in subject between the two actions.
- If you want to specify the subject, use a prepositional phrase (e.g., avant de moi partir – “before I leave”), but this is less common and more formal.
Understanding “avant que”: The Subjunctive Structure
“Avant que” introduces a subordinate clause and is followed by a verb in the subjunctive mood. This structure is used when the subjects of the two clauses are different.
When to Use “avant que”
Use “avant que” when you want to express that one action happens before another action performed by a different subject. The verb in the subordinate clause must be in the subjunctive.
- Je veux finir avant que tu n’arrives. (I want to finish before you arrive.)
- Nous devons partir avant que la pluie ne commence. (We have to leave before the rain starts.)
The Importance of the Subjunctive
- After “avant que,” the verb is always in the subjunctive because it expresses a possibility or something that hasn’t happened yet.
- You will often see the “ne explétif” (an extra “ne” without negative meaning) in formal French after “avant que,” though it’s optional in spoken French.
Quick Comparison Table
| Expression | Structure | Example | When to Use |
|---|---|---|---|
| avant de | avant de + infinitive | Je pars avant de manger. | Same subject for both actions. |
| avant que | avant que + subjunctive | Je pars avant que tu n’arrives. | Different subjects for each action. |
Common Mistakes and How to Avoid Them
- Mixing up the structures: Remember, use “avant de” with infinitives and “avant que” with the subjunctive.
- Forgetting the subjunctive: After “avant que,” always check if the verb needs to be in the subjunctive mood.
- Using “avant de” with different subjects: If the subjects differ, switch to “avant que.”
