Questions & Answers about Я тебе верю.
Because верить normally takes the dative case for the person you believe or trust.
- ты = nominative, used for the subject
- тебя = accusative/genitive
- тебе = dative
So in Я тебе верю, я is the subject, and тебе means to you in a grammatical sense.
A very literal breakdown is:
- Я = I
- тебе = to you
- верю = believe / trust
Russian says it more like I believe to you, even though natural English is I believe you.
Верю is the 1st person singular form of верить.
That means:
- верить = to believe / to trust
- я верю = I believe / I trust
A few present-tense forms:
- я верю = I believe
- ты веришь = you believe
- он / она верит = he / she believes
- мы верим = we believe
- вы верите = you believe
- они верят = they believe
So the ending -ю here tells you the subject is I.
