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!?

In spoken French, do Conditionnel Passé and Le Futur Antérieur sound noticeable different? It seems like it would be confusing.

"In the first half of the week" the acceptable translation is Dans (or durant or pendant) la première moitié though above it says "Durant".  However, "In the second half of the week", "Dans" and "moitié are both marked as incorrect with "moitié" is replaced by "partie".  Could you please explain the differences as I don't understand them.

I often find that if I have a lesson I want to retest on it won't let me & says:

"To kwiz this lesson again, save it to a notebook and kwiz against it until you have nailed it."

but when I add it to the notebook it then says:

"This lesson is already in your notebook. Go to your notebook now to kwiz this topic as many times as you like."

apologies if this has been asked before, but I did search & check the FAQ but didn't find anything.

many thanks  :)

All of the examples with du chocolat or du cafe translate as some chocolate or some coffee, but in my kwiz it has it listed as nearly correct. I don't really care about the points, but it's confusing for the quiz to not line up with the lesson.

The question was: "Les parents sont ____________ la Poste."  The hint sais that the parents were at the post office.  My response was "Les parents sont dans la Poste."  QUIZBOT said that the correct response is "Leas parenat sont a (with accent) la Poste.  Why is "dans" not correct?    

I know that typically, retourner is used to mean "to go back" and rendre is used to mean "to give back." But on this page: https://www.lawlessfrench.com/grammar/auxiliary-verbs-2/ , which discusses using variable auxiliary verbs in the passé composé, it mentions that retourner can also be used transitively and in that case, it changes its meaning to "to give back." So in the passé composé, can retourner be used in the same way that rendre is?

For example, would both of these be correct?

1. J'ai rendu le livre à la bibliothèque.

2. J'ai retourné le livre à la bibliothèque.
