Homophones share pronunciation, homographs share spelling, and homonym is the umbrella term covering words that coincide in sound, spelling, or both.

Doing CRediT right? Don’t stop at the statement.

A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.

Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.

Where homographs fit in

The third member of this family is the homograph — words that share spelling but differ in meaning, and sometimes in sound, such as the bow of a ship versus a bow of ribbon, or lead the metal versus to lead a team. Homographs are the look-alike counterpart to homophones (the sound-alikes), and both sit under the umbrella term homonym. A neat way to keep the trio straight: homo- means "same" in all three; the second part tells you what is the same. Homophone has phone, so same sound; homograph has graph, so same writing; and homonym has onym (name), the broad "same name" that covers the others. A word can belong to more than one category at once — bear (the animal) and bear (to carry) are spelled and sounded alike, so they are homographs, homophones and homonyms together.

Common questions

FAQ

What is the simplest way to tell them apart?+

Look at the second half of each word. Homophone ends in -phone (sound), so homophones sound the same: their and there. Homograph ends in -graph (writing), so homographs are written the same: the bow of a ship and a bow of ribbon. Homonym ends in -nym (name) and is the umbrella term covering both sound-alikes and look-alikes.

Can a pair of words be all three at once?+

Yes. When two words share both spelling and pronunciation, they are homographs (same spelling), homophones (same sound) and homonyms in the strict sense all at once. Bank (the side of a river) and bank (a financial institution) are an example — identical in spelling and sound, different in meaning.

Is "homonym" sometimes used to mean just one of the others?+

Yes, usage varies. In the broad sense, homonym is the umbrella for homophones and homographs. In the strict sense, it names only words that match in both spelling and sound. Both uses are accepted, so it is worth checking which sense a source intends.
