Questions & Answers about Моя сестра любит создавать уютную атмосферу дома.

Why is it моя сестра and not мой сестра?

Моя is the feminine form of мой (“my”).

In Russian, possessive pronouns agree in gender, number, and case with the noun they modify.

• сестра (sister) is:
  • feminine,
  • singular,
  • nominative (subject of the sentence).

So you must use the feminine nominative singular form of мой → моя.

Compare:

• мой брат (my brother) – брат is masculine.
• моя сестра (my sister) – сестра is feminine.
• моё окно (my window) – окно is neuter.
• мои друзья (my friends) – друзья is plural.

What case is сестра in, and why?

Сестра is in the nominative singular.

The nominative case is used for the subject of the sentence – the person or thing that performs the action.

Here:

• Моя сестра = My sister is the subject.
• She is the one who “likes to create a cozy atmosphere”.

So she must be in nominative case: сестра, not сестры, сестре, etc.
