And here we come back to something that causes me headache. What form of adjective I must use with the polite plural?
If I want to say to a cute girl - You are extremely beautiful-> Вы безумно | весьма красива или красивы?
If I want to say to an old businessman = - You are extremely clever-> Вы очень/чертовски умён или умны?
- In Greek this is not an issue. The adjective in the polite form should always be in singular. In Russian I think no.
