Heteronym (linguistics)

A heteronym (also known as a heterophone) is a word that is written identically but has a different pronunciation and meaning. In other words, they are homographs that are not homophones. Thus, row (propel with oars) and row (argument) are heteronyms, but mean (intend) and mean (average) are not (since they are pronounced the same). Heteronym pronunciation may vary in vowel realisation, in stress pattern (see also Initial-stress-derived noun), or in other ways:

Most heteronyms are doubles. Triple heteronyms are extremely rare; two examples, sin and mobile, are listed below. Proper nouns can sometimes be heteronyms. For example, the final syllable of is pronounced like the word in by residents of that state in the United States, while in the name of the village of Oregon in Wisconsin, the final syllable is pronounced like the word on. Other examples include local pronunciations of Cairo, GA, Versailles, KY, and Milan, TN. There are also pairs which include both initialisms and regular words, e.g., US and us.

Heteronyms can also occur in non-alphabetic languages. For example, the Chinese character 行 can be pronounced háng, meaning "profession", or xíng, meaning "OK".

"Heterophone" literally just means "different sound", and this term is sometimes applied to words that are just pronounced differently, irrespective of their spelling. Such a definition would obviously include virtually every pair of words in the language, so "heterophone" in this sense is normally restricted to instances where there is some particular reason to highlight the different sound. For example, puns normally involve homophones, but in the case of heterophonic (or imperfect) puns, the two words sound different, and yet similar enough for one to suggest the other (for example, mouth and mouse).
