Questions & Answers about Эта игра интересная и весёлая.
In Russian, the word for this has to agree with the noun in gender, number, and case.
- игра (game) is:
- feminine
- singular
- in the nominative case (subject of the sentence)
So you must use the feminine nominative singular form of this:
- этот – masculine (for words like стол – table)
- эта – feminine (for words like игра – game)
- это – neuter (for words like окно – window)
Because игра is feminine, you say эта игра, not это игра or этот игра.
