* It's a misspelling: Perhaps you meant a different word, like "Natasha" or "Nadia".
* It's a regional or niche term: It might be a word specific to a certain dialect, culture, or field.
* It's a made-up word: It could be a fictional name, a code word, or a creative invention.
To help me understand what you're looking for, please provide more context:
* Where did you encounter this word? (e.g., a book, a song, a conversation)
* What language do you think it might be from?
* What is the surrounding text or situation?
This will help me determine the meaning of "Naduah" more accurately.
