Homophones: Words that sound the same but have different meanings and spellings.
* Examples:
* "to, too, two"
* "there, their, they're"
* "see, sea"
Homographs: Words that are spelled the same but have different meanings and may or may not sound the same.
* Examples:
* "bow" (a knot) and "bow" (to bend at the waist)
* "lead" (a heavy metal) and "lead" (to guide)
Relationship:
While not opposites, they are related in the sense that both deal with words that share similarities.
* Homophones focus on sound.
* Homographs focus on spelling.
It's important to note that a word can be both a homophone and a homograph. For example, "bow" (a knot) and "bow" (to bend at the waist) are both spelled the same and sound the same, making them both homophones and homographs.
