De Or Du

Hi, I would like to know why In Lesson 4.4 (at the restaurant) the guest asks for " Un verre de vin blanc" intstead of "Un verre du vin blanc". Thanks

Hi there, Basically, "de" or "d' is "of" and "de l' is "some", just like "du" in a way. Have a look at the following examples: "une bouteille d'eau" (a bottle OF water) Je voudrais de l'eau (I would like SOME water) " une bouteille DE vin (a bottle OF wine) "je voudrais DU vin (I'd like some wine) I hope that helps. :D
