If you break heterograph apart:
Hetero- means different, other
-graph means drawn or written
This means a heterograph is written differently — with a different spelling. It does not mean the same but does sound the same.
Grammar Explanations is…
…an evolving list of the structural rules and principles that determines where words are placed in phrases or sentences as well as how the language is spoken. Sometimes I run across an example that helps explain better or another “also known as”. Heck, there’s always a better way to explain it, so if it makes quicker and/or better sense, I would appreciate suggestions and comments from anyone on an area of grammar with which you struggle or on which you can contribute more understanding.
