"The man's fingernails are black."

Translation: 남자의 손톱이 검어요.

The is not hint for fingernails. I just used the process of elimination

[BobaBunny5]

Could you just say 남자는, wouldn't it be more natural not to use the possessive particle here since it would be apparent that it is his hands anyways?

[ElielF4]

He gotta go to a manicure or a doctor if he wants to keep those fingernails

[Woody.dinero]

We don't say 검어요... Usually use 까매요
