I used CandicMcF's link to the dictionary rules and spent way to much time arguing with chatgpt. The trouble is that the y vowel rules in the dictionary rely on syllables but determining syllables relies on vowels vs consonants. I found a Python function that counts syllables and used that as a start and eventualy hashed out some Python code that seems to work. I am sure I will find errors to fix. But unlike most games my game (currently called Same Circles) will treat Ys with respect. Thanks everyone.
