Can you please explain the differences between dans, a, and de? I took French more than 50 years ago and I never learned the differences.

dans -- in
à -- at (but has many different functions and meanings)
de -- of/from (also has many different meanings)

I suggest you stick with the lessons kwiziq chooses for you. They will lead you where you need to go and also cover those three prepositions.

Hi Lois,

I can recommend French Grammar ISBN 0-19-860341-X within which you will find all the answers that are not covered in the lesson Un/une = A or An (French Indefinite Articles)
