What does homonymy mean?
Homonymy is the linguistic phenomenon in which a single word form can have different meanings or refer to different things. It may arise when words are spelled alike, pronounced alike, or both. For example, “bank” can refer to a financial institution, the side of a river, or a row of clouds, and “to,” “too,” and “two” sound identical while functioning as distinct words. Homonymy is especially important in writing, where an identical spelling can conceal a change in meaning, and in speech, where pronunciation may make several written forms indistinguishable. Context normally resolves the intended sense, but when it does not, ambiguity or confusion can result. Lexicographers distinguish the individual words involved from the broader relationship among them: “homonym” names a word sharing another’s form, while “homonymy” names the phenomenon itself.
nounHomonymy is the phenomenon in which words with the same written or spoken form have different meanings or refer to different things. It can involve homographs, which share a spelling, homophones, which share a pronunciation, or both.
- The phenomenon of two or more words having the same spelling but different meanings, as with “bat” meaning a flying mammal or a piece of sports equipment.
- The phenomenon of two or more words having the same pronunciation but different spellings or meanings, as with “to,” “too,” and “two.”
- The use of a single word form to refer to different people, objects, or ideas, with the intended referent determined by context.
"The context-dependent meanings of the word “bank” illustrate homonymy."
"Homonymy can make a sentence unexpectedly humorous or confusing when context does not make the intended meaning clear."
"The dictionary discusses the homonymy of “rose,” which can name a flower, a past tense form of “rise,” and a colour."
The plural is used for different instances or kinds of homonymy.
"The study compares several homonymies created by changes in pronunciation over time."
The same word can point to entirely different worlds: “bank” may lead us to money, a riverbank, or even a bank of clouds.

Where does homonymy come from?
Homonymy comes from Greek homos, meaning “same,” and onoma, meaning “name” or “word.” The related English terms “homonym” and “homonymous” were formed in the early 19th century from these Greek elements. The same Greek root onoma also appears in words such as “synonym” and “anonymous,” although their prefixes give them different meanings.
How homonymy is actually used
In descriptive linguistics, homonymy is a broad category that includes homographs, homophones, and words sharing both form and meaning distinctions. The term is more technical than everyday “ambiguity,” which can also result from grammatical structure, punctuation, or an unclear speaker’s intention.
Easily confused with homonymy
A homonym is an individual word that shares its spelling or pronunciation with another word, whereas homonymy is the relationship or phenomenon among such words.
A homograph is a word that has the same spelling as another; homonymy is the broader phenomenon that includes both spelling and pronunciation matches.
A homophone is a word that sounds like another word, while homonymy refers more generally to the shared form and differing meanings or referents.
