This document discusses homophones in morphology. It defines a homophone as a word that sounds like another word but has a different meaning and spelling. The document notes that in morphology, homophones must be remembered as different morphemes. It provides examples of homophones like "sale/sail" and "meet/meat" to illustrate this point. The document also explains that this is true for bound morphemes like verbal, noun plural, and noun possessive suffixes that are homophonous but represent different morphemes.
