Этот is the masculine singular form of “this” and must agree with the noun подкаст in gender and number.
The forms of “this” in the nominative are:
- Этот – masculine singular (for он nouns)
- Эта – feminine singular (for она nouns)
- Это – neuter singular (for оно nouns)
- Эти – plural (for они nouns, any gender)
