Questions & Answers about Мой брат очень активный и любит спорт.
In Russian, the verb to be (быть) is normally omitted in the present tense when linking a subject with a noun or adjective.
So instead of saying something like Мой брат есть очень активный, Russian just says:
- Мой брат очень активный. – literally: My brother very active.
In the past and future, a form of быть appears:
- Мой брат был очень активным. – My brother was very active.
- Мой брат будет очень активным. – My brother will be very active.
Because брат (brother) is grammatically masculine, and the possessive pronoun must agree with the noun it modifies.
- мой – my (masculine, nominative)
- моя – my (feminine, nominative)
- моё – my (neuter, nominative)
- мои – my (plural, nominative)
So:
- мой брат – my brother
- моя сестра – my sister
- моё окно – my window
- мои друзья – my friends
