When giving commands like Buy them! or Call her!, the French pronouns le, la, and les are tied to the verb with a hyphen!
But if you're telling someone not to do something, le, la, and les come before the verb.
We've seen that some adjectives go before the word that they describe.
We've also seen that you need to put des before plural nouns!
And if both these happen together? Use de before the adjective instead of des!
