What is the word for trust in greek?

There isn't one single perfect translation for "trust" in Greek, as the best word depends on the nuance you want to convey. Here are a few options with slightly different meanings:

* Πίστις (pistis): This is probably the closest single word and often translates to "faith," "belief," or "trust." It implies a strong belief in someone or something, often with a religious connotation, but can also be used in secular contexts.

* Εμπιστοσύνη (empistosýni): This word means "confidence" or "trust" and is a more general term for reliance and faith in someone or something's reliability. It's often a better choice for secular contexts.

* Ελπίδα (elpída): This word means "hope" but can sometimes imply a trusting expectation of a positive outcome.
