Questions & Answers about Я хочу вернуться домой раньше.
Word by word:
- Я – I
- хочу – want
- вернуться – to return, to come back (perfective infinitive)
- домой – home in the sense to home (direction)
- раньше – earlier
So the structure is literally: I want (to) return home earlier.
Russian often shows direction with special adverb-like forms instead of a separate word like “to”.
- дом – house, home (basic noun form)
- домой – to home, (going) home
So домой already includes the idea of “to”.
You don’t say к домой or в домой; you just use домой by itself:
- Я иду домой. – I’m going home.
- Мы поедем домой. – We’ll go home (by transport).
