Questions & Answers about Моя подруга сказала, что этот детектив стоит перечитать из-за деталей, которые сначала кажутся неважными.
Because the subject is подруга, which is a feminine noun.
- моя подруга = my female friend
- In the past tense, Russian verbs agree with the subject in gender:
- сказал = he said
- сказала = she said
- сказало = it said
- сказали = they said
So Моя подруга сказала means My friend said, with both the pronoun and the verb showing that the friend is female.
It can mean either, depending on context.
- подруга = a female friend
- In some contexts, it can also mean girlfriend
Here, since the sentence is neutral and about recommending a book, it most naturally means female friend.
This is a common point for English speakers because English separates friend and girlfriend, while Russian sometimes relies on context.
