"Do you put some sugar in the coffee?"
Translation:Metti dello zucchero nel caffè?
"Do you put some sugar in the coffee?" is an ungrammatical and ambiguous English inquiry. It sounds like they're asking if the coffee is served with sugar in it already. The grammatically correct English construction would be, "Do you put sugar in the coffee?" or "Is the coffee pre-sweetened?" Either way, this is an odd inquiry since coffee is typically brewed black.
If the diner wants the waiter to bring him sugar so the diner can add it to his own cup of coffee, he would ask, "May I have sugar with my coffee?"
The diner could also ask the waiter to add sugar to his cup of coffee, "Would you please put some sugar in my coffee?" or " Could you please add sugar?"
Maybe the inquiry is being asked by the waiter. If this is the case, the waiter would ask, "Would you like sugar in your coffee?"
It is important that the English inquiry is correctly written because it affects the correct Italian translation. I'm sure the Italian inquiry for "Is the coffee pre-sweetened?" is different from "Please, put some sugar in my coffee?"
"Dello = di + lo" = of the (in this case = some) ("lo" is a definite article that is used before the so-called impure consonants, that is, s+consonant, gn, ps, x or z) , while "dallo = da + lo = from the" (Vengo dallo zoo = I come from the zoo)
dell' = di + l' (when the next word is starting with a vowel, Bevo dell'acqua / I drink some water)
(I know this is very late.) To clarify what dnovinc said, in Italian, using "di" + an article (like il, lo, etc.) becomes the English word some. I was taught in class that it is an unrelated meaning, which makes sense to me, because "of the" is a sepatate phrase than "some" in English. So "some sugar" is "dello zucchero" and "some apples" is "delle mele".
The correct answer assumes "you" is translated as "one", i.e. third person singular. However, there is nothing in the sentence to indicate that "you" cannot refer to second person singular, or second person plural. I put the latter, and was marked wrong with correct answer given as "should have used lei!"
