Heterograph

A homophone is a word that is pronounced the same as another word but differs in meaning, and may differ in spelling. The words may be spelled the same, such as (flower) and (past tense of "rise"), or differently, such as carat, caret, and carrot, or to, two, and too. Homophones that are spelled the same are also both homographs and homonyms. Homophones that are spelled differently are also called heterographs. The term "homophone" may also apply to units longer or shorter than words, such as phrases, letters or groups of letters that are pronounced the same as another phrase, letter or group of letters.

A word or unit with this property is said to be "homophonous". "Homophone" derives from the Greek homo-  (ὁμο‑), "same", and phōnḗ (φωνή), "voice, utterance".

Homophones are often used to create puns and to deceive the reader (as in crossword puzzles) or to suggest multiple meanings. The last usage is common in poetry and creative literature. An example of this is seen in Dylan Thomas's radio play Under Milk Wood: "The shops in mourning" where mourning can be heard as mourning or morning. Another vivid example is Thomas Hood's use of "birth" and "berth" and "told" and "toll'd" (tolled) in his poem "Faithless Sally Brown":

In some accents, various sounds have merged in that they are no longer distinctive, and thus words that differ only by those sounds in an accent that maintains the distinction (a minimal pair) are homophonous in the accent with the merger. Some examples from English are:

Wordplay is particularly common in English because the multiplicity of linguistic influences offers considerable complication in spelling and meaning and pronunciation compared with other languages.
