* A misspelling: There might be a similar word you're thinking of, like "predate" or "pre-date," which means to be earlier in time or to date something before a certain time.
* A made-up word: It could be a slang term, a specific term used in a niche field, or even a fictional word from a book or game.
To help me understand what you mean, could you please provide more context? For example:
* Where did you encounter this word?
* What was the sentence or phrase it was used in?
* What is the general topic or subject?
With more information, I can help you figure out the intended meaning of "pradage."
