It's possible that:
* It's a misspelling: Perhaps you meant "healthy", "elfin", or "helpful"?
* It's a nickname or slang term: If it's something you heard, try asking the person who used it for the correct spelling.
* It's a made-up word: If you're creating a fictional character or concept, then you get to decide how to spell it!
Let me know if you can give me more context and I might be able to help further. 😊
