Questions & Answers about Я люблю фотографировать друзей в парке.
Because друзей is the accusative plural form of друзья (friends).
- The base word is:
- друг – friend (singular, nominative)
- друзья – friends (plural, nominative)
- After любить (to love / to like), the object must be in the accusative case:
- люблю кого? что? – I love whom / what?
- The accusative plural of друзья is друзей:
- Я люблю друзей. – I love (my) friends.
For animate masculine nouns (people, animals), the accusative plural form is the same as the genitive plural, which is why друзей looks different from друзья.
