Questions & Answers about Quanta carne vendono qui?
Why is it "Quanta" instead of "Quanto"?
Since carne ends in "-e", how do we know it's feminine to match with Quanta?
Where is the word for "they" in this sentence?
In Italian, subject pronouns like loro (they) are usually dropped because the verb ending already tells you who is doing the action. The -ono ending on vendono (from the regular verb vendere, to sell) tells us that "they" are the ones selling.
