A homonym is a word that is spelled the same as another word but has a different meaning and often a different pronunciation. While there are words that sound very similar to "maize", such as:
* maze: a confusing network of paths or passages
* mayze: an archaic spelling of "maze"
These are not true homonyms as they are spelled differently.
"Maize" itself is a unique word, and there are no other words in the English language that share both the same spelling and pronunciation.
