The subjunctive
Sample lesson, B2 grammarThe rule
After doubt, emotion, necessity or will (il faut que, je doute que, je veux que), the second verb shifts into the subjunctive. The action is not a fact, it is a wish, a fear or a requirement.
In practice
Il faut que tu fasses tes devoirs.
Not "tu fais". It is not a statement of fact, it is a requirement. The mood carries the meaning, not just the tense.
The mistake almost everyone makes
Memorising the conjugations without learning the triggers. Students conjugate perfectly and still say the wrong thing after penser que, which takes the indicative.
Practice, the way you will use it
We build five real sentences about your actual week, one wish, one doubt, one requirement, until the trigger-to-mood reflex is automatic rather than memorised.
