црна
"Црна" means "black" in English.
In this sentence, 'црна' is used as an adjective describing the color of the noun 'jakna' (jacket). It is in feminine singular form to agree with the gender and number of the noun.
Јас носам црна јакна денес.
I am wearing a black jacket today.
In this case, 'црна' again functions as an adjective modifying 'коса' (hair), describing its dark color.
Таа има црна коса.
She has black hair.
Here, 'црна' describes 'листа' (list), metaphorically referring to a list of blacklisted individuals. The meaning is figuratively negative.
