I'm wondering about using 'des' before noun. I know that if the adjective was before the noun we must use 'de', but can anyone tell me why did we use 'des' not 'de' in this sentence :

L'organisation travaille sur des grands domaines


In fact, both are correct. Moreother de sound better in this case IMHO.

  • It depends on the end of the sentence : does it end after "grands domaines" (-> de) or is there a subordinate clause (-> des)

  • @YohannV. I don't understand, what you mean exactly, could you elaborate and give an example ?

  • If you have a sentence like L'organisation travaille sur de grands domaines. you will prefer to use de because you don't add more informations. If you want to say more : L'organisation travaille sur des grands domaines, qui bien que variés ont tous le même objectif. you use des because this nominal group will be explained into the subordinate clause.
