What does the word creida mean?

"Creida" is not a word in English or any major language. It's possible it's:

* A misspelling: Perhaps you meant "creed" or "credo", which both mean a statement of belief or principle.

* A word from another language: Could you provide more context about where you encountered this word? Knowing the language it's from will help me understand its meaning.
