Hello, perhaps i missed this/am not understandng something: is there a rule for en versus de usage? eg une robe de satin or une robe en satin? 

In regards to the last section about food, when do you use 'À/Aux' compared to when you should use 'De'?

Why une brosse a dents and not aux because dents is plural?

This was a question in one of the quizzes:

Il m'a offert une boîte ________ bijoux pour ranger mes colliers.

The difference is the same as in English: une glace de marrons -- an ice cream made from chestnuts (the main ingredient is chestnuts)

une glace aux marrons -- an ice cream made with chestnuts (chestnuts are not the main ingredient)    

This nuance wasn't clear from the lesson above. How does one distinguish 'from' versus 'with' in such cases?

as jewellery is plural why is a used rather than aux?

Bonjour,

I am looking over this lesson and was making compound words and I made a sentence and was hoping  you can tell me if it is correct?

Doghouse

Une maison à chien

Thanks

Nicole

Is cuillère à thé a fixed phrase meaning a teaspoon for measuring? The lesson says à generally means what something is used for, however, this phrase would then mean "a spoon for tea," not a "teaspoon."

Could you add some clarification re: wedding bells, baseball cap, tennis racquet, door knob, golf club, soccer ball, soccer field, sunglasses, Christmas tree, water tank, bus stop, fire truck, etc.

By your lesson, these should all be “à” (what something is designed for), but in fact this whole genre is “de”.

Specifically, why is it “boîte à bijoux” and not “boîte de bijoux” ? Other than convention.

Clearly, these are not just a few exceptions, but an entire class of compound nouns (open form, noun+noun) that is not covered in the lesson.

Thank you.

In the grammar lesson, it explains that you can use either "en" or "de" in "un sac .... cuir". So to avoid confusion,  would it not be better to show that both "en" and "de" are also both acceptable answers in "Je possède un blouson _____ cuir". Or are they?
