Questions & Answers about Vaša pitanja su loša.
Why do Vaša and loša end in "-a"? Doesn't that usually mean they are feminine singular?
It can, but here it marks the neuter plural! The noun pitanje (question) is neuter. When neuter nouns become plural, they take the "-a" ending to become pitanja. Any adjectives describing them must match, so vaš (your) and loš (bad) also take the "-a" ending to become vaša and loša.
Since pitanja ends in "-a", how can I tell it's neuter plural and not a feminine singular noun?
The secret is in the verb! The verb here is su (are), which is plural. If this were a feminine singular noun, the verb would be je (is) instead. For example: Vaša kava je loša (Your coffee is bad).
What is the singular form of Vaša pitanja su loša?
It would be Vaše pitanje je loše. Notice how the neuter singular noun pitanje ends in "-e". Because of this, the adjectives take the neuter singular ending "-e" (Vaše, loše), and the verb changes to the singular je.
Could I put the word su right after Vaša?
