Thsee are what I think are correct:

Je veux le café = I want the coffee

Je veux le café = I want coffee

Je veux du café = I want some coffee

Ils veulent des cafés = They want coffees

Ils veulent du café = They want some coffee

ILS veulent le café = They want coffee

Ils veulent de café = They want a coffee.

I think these are all correct grammar, depending on the situation.

Please correct me if I'm wrong.

Is récupérer interchangeable with acheter? Can I use récupérer for clothes shopping? 

e.g. Je vais récupérer une robe

What is the difference of  "savoir" and "connaître"? They both mean "to know", right? When should I use which one?
