For negative sentences. Is it Elle n'aime pas les jupes or Elle n'aime pas des jupes? Is there a rule for using les/des for negatives?

Bonsoir, Yan! Again it depends upon whether or which to say "she doesn't like THE skirts" or "She doesn't like skirts." The rule is "if you want the DEFINITE article you have certain skirts in mind. If you use the PARTITIVE it's like saying "some, any, not any, etc."

And the usual rule is "pas de" so the 2nd would be "Elle n'aime pas de jupes." With the negative just memorize "pas de" and/or "pas d'."

To answer your first question, the correct negative sentence is "Elle n'aime pas les jupes."

Regarding the use of "les" and "des" in negative sentences, there is a rule to follow. In French, when expressing a negative opinion or preference about something in general, you use the definite article "les" (the). This is why you use "les" in the sentence "Elle n'aime pas les jupes," which means "She doesn't like skirts" in English.

On the other hand, when expressing a negative opinion or preference about an unspecified quantity or type of something, you use the partitive article "des" (some). For example, "Elle n'aime pas des jupes" would mean "She doesn't like some skirts" in English. However, this sentence sounds unnatural in French because typically, the definite article is used to express general preferences about things.

In summary, the rule is to use "les" in negative sentences when expressing a general dislike towards something, and to use "des" when expressing a specific negative opinion about an unspecified quantity or type of something.
