It's possible that you're thinking of a similar-sounding word, or that the spelling is incorrect.
Here are some possibilities:
* Kai: This means "food" in Māori.
* Kaia: This could be a personal name, though it's not a common one.
* Kai-a: This could be a compound word, where "kai" is combined with another word.
If you can provide more context or the full word/phrase, I might be able to give you a more accurate answer.
