Final answer:
A homonym is a word that sounds like another word but may be spelled differently and has a different meaning.
Step-by-step explanation:
A homonym is a word that sounds like another word but may be spelled differently and has a different meaning. For example, the words 'there,' 'their,' and 'they're' are homonyms. They all sound the same, but they have different spellings and meanings.
Another example is the homonym pair 'to,' which can be spelled as 'to' or 'two.' 'To' is a preposition, while 'two' is the number.
