Questions & Answers about Моя подруга купила жёлтый тюльпан для бабушки.
Because подруга is a feminine singular noun, and the possessive word my has to agree with it.
- мой = masculine singular
- моя = feminine singular
- моё = neuter singular
- мои = plural
So:
- мой друг = my male friend
- моя подруга = my female friend
In this sentence, моя matches подруга.
Подруга is the subject of the sentence, so it is in the nominative case.
The nominative is the basic dictionary form, and it is usually used for the person or thing doing the action.
Here:
- Моя подруга = the person who did the buying
So подруга stays in its nominative singular form.
