* It's a misspelling: Perhaps you're thinking of a different word, possibly with a similar sound. Could you be thinking of a word like "maidin" (morning)? Or perhaps a word related to maidenhood? More context would be helpful.
* It's a dialectal word or archaic form: Irish has many dialects, and some words might only be used in specific regions or be outdated.
* It's a made-up word: It's possible the word is not actually Irish.
To help me find the correct meaning, please provide more information:
* Where did you encounter this word? (Book, song, conversation, etc.)
* What was the context? (The sentence it was used in would be very helpful.)
With more information, I can give you a more accurate answer.
