Breakdown of Моя сестра умеет готовить вкусный борщ.
Questions & Answers about Моя сестра умеет готовить вкусный борщ.
Because сестра is a feminine singular noun, and the possessive pronoun my has to agree with it.
So:
- мой = masculine singular
- моя = feminine singular
- моё = neuter singular
- мои = plural
Since сестра is feminine, you say моя сестра.
Умеет is the 3rd person singular form of the verb уметь, which means to know how to or to be able to (because of skill).
The subject is моя сестра = my sister, which is she, so the verb must match she:
- я умею = I know how to
- ты умеешь = you know how to
- он / она умеет = he / she knows how to
- мы умеем
- вы умеете
- они умеют
So моя сестра умеет means my sister knows how to / can.
