Q:

"Whisky prices" in Italian

I am looking for the correct translation of "whisky prices". It looks like prezzo is singular and prezzi is plural. 
Now I am wondering if one needs an article or a declension to form this phrase in Italian. I translated it as whisky prezzi or prezzi del whisky. Which one of these two forms is correct? Or is there another form perhaps?

A:

Prezzi del whisky is the correct form, whisky prezzi is surely an error.
This type of preposition (del) is a preposition combined with an article (preposizione articolata) and is built by a simple preposition + definite article.

Take care in Italian the word whisky is used for both singular and plural.
