Synonyms1, 2, 3. Three similar terms—
homophone, homograph and
homonym —designate words that are identical in pronunciation, spelling, or both, while differing in meaning and usually in origin. {*newpara}
Homophones (“same” + “sound”) are different words that sound alike, whether or not they are spelled alike. Thus
pair “two of a kind,”
pare “cut off,” and
pear, the fruit, are
homophones because they sound exactly the same, even though each is spelled differently. But
bear “carry or support” and
bear, the animal, are
homophones that not only sound alike but are also spelled alike. {*newpara}
Homographs (“same” + “writing”) are different words that are spelled the same but may or may not have the same pronunciation. The
homographs sound “noise,”
sound “healthy,” and
sound, “a body of water,” for example, are spelled and pronounced the same way. However, words with the same spelling but different pronunciations are also
homographs. Familiar examples are the pairs
row rōroʊroh “line” and
row rouraʊrou “fight” as well as
sewer so̅o̅·ərˈsu

ərsoo-er “conduit for waste” and
sewer sō·ərˈsoʊ

ərsoh-er “person who sews.” Their identical spellings define them as
homographs no matter how they are said. {*newpara} The word
homonyms (“same” + “names”) is, strictly speaking, either a synonym for
homophones or a name for words that are at once
homophones and
homographs —alike in both spelling
and pronunciation—such as the two words spelled
b-e-a-r and the three spelled
s-o-u-n-d. As a practical matter, however, the terms
homophone, homograph and
homonym are often distinguished from one another by the contexts in which they are found.
Homophone and
homograph —the first focused on sound and the second on spelling—appear primarily in technical or academic writing, where fine distinctions are important. The more familiar word
homonym heard in classrooms from early grades on, has become an all-inclusive term that describes not only words that are both homophonic and homographic, but words that are either one or the other. In common parlance, then, words that sound alike, look alike, or both, can be called
homonyms.
