In the statement "mon fils a de grandes oreilles" , why is it not "DES grandes oreilles"? Ears is plural, and "de" is the article, and "grand" is following a feminine plural suit.... I've noticed this with other items, mostly body parts, like toes, fingers, eyes. They all use a plural article "les" but when describing them, it turns to "de"

If I said "he had cats" it would be "il a des chats", right? What am I not getting!?

I'm learning a piece of music by the composer Georges Hüe.  How is this last name pronounced?  From the description I saw on https://www.lawlessfrench.com/pronunciation/dieresis/ I am guessing that the "H" is silent, the "ü" is pronounced as a standard "u," and the "e" is voiced instead of silent.  Is that correct?  (If someone knows IPA, then perhaps that would be a good way to answer?)

"il n'est jamais alle nulle part." This was one of the examples given in the lesson, but I  thought that it would be wrong to use *jamais* since "ne ... nulle part" is a negation of its own just like "ne .... aucune"

Should je suis toujours anxieux also be an accepted answer compared to je suis toujours nerveux? Or perhaps anxieux is considered more a medical condition and too strong in this context?
