French negative form
Negative describes a statement that uses a grammatically negative construction (as opposed to affirmative).
In French, the negative form requires at least two words: ne ... pas, ne ... jamais, ne ... plus, etc.
La maison n'est pas grande. - The house isn't big.
Je ne mange jamais d'épinards. - I never eat spinach.
Elles n'ont plus de sucre. - They don't have any sugar left.
Elle ne lit rien. - She reads nothing.
Note: The term "negative" refers to the grammatical construction, not the meaning of the sentence.
Questions (interrogative statements) and commands (imperative statements) can also be negative:
Pourquoi ne répond-il pas ? - Why is he not answering?
Ne marchez pas sur la pelouse ! - Don't walk on the grass!
