"I trust you."

[ShaoxuanLi]

what's the difference between εμπιστεύομαι και πιστεύω; Can they be used interchangeably?

[troll1995]

Εμπιστεύομαι is "trust, whereas πιστεύω is "believe". Πιστεύω σε can be used with the meaning of "trust" the same way "believe in" does, with the same differences in meaning. So Πιστεύω σε 'σένα=i believe in you, σε εμπιστεύομαι=i trust you, πιστεύω στις νεράιδες=i believe in fairies (no "trust" meaning here), but εμπιστεύομαι τις νεράιδες=i trust the fairies.

How do you know its Σε εμπιστευνομαι and not Σου εμπιστευνομαι?

[Gitirana]

Isn't correct "πιστεύω σε"? or "σε πιστεύω"...

[D_..]

"πιστεύω σε" becomes πιστεύω σε (κάτι) where σε=in. Σε is a preposition translated in English as in, to, for, depending on syntax.

"σε πιστεύω": in this case σε=you, the short/weak form of the pronoun εσύ in the accusative. Long/strong form being εσένα.

So if you want to say 'I believe in you' you say Πιστεύω σε (ε)σένα or Σε πιστεύω.
