Homographs are words that are spelled the same but have different meanings. They aren't necessarily pronounced the same.
Example one, different pronunciation: Tear
- To rip or shred- verb
- When crying, what falls from one's eyes- noun
Example two, same pronunciation: File
- A compartment to store things, usually papers
- A tool to incrementally smooth a surface such as a nail file for fingernails, or a metal file for manufacturing or construction purposes.
Homographs are different from homonyms. Homonyms must be spelled the same AND pronounced the same (but have different meanings).
