Oh, what a fun challenge! Hawaiian language doesn't have many words that start with X, Y, or Z, but I can share a few. "X" is not a common letter in Hawaiian words, but you might find words like 'xemena' which means 'chemainus.' For "Y," you could look for words like 'yaki' which means 'to grill.' And for "Z," you might come across 'zaboka' which means 'avocado.' Keep exploring the beauty of language, my friend!
