What does heteronym mean?
A heteronym is a noun for a word that is written the same as another word but pronounced differently. Common examples include "read," pronounced /riːd/ in the present tense and /rɛd/ in the past, and "lead," which changes sound and grammatical function between a verb and a noun. The word is especially useful in pronunciation instruction, linguistics, poetry, and word games because it identifies a distinction that spelling alone cannot show. Often the meanings also differ, but pronunciation is the defining feature. The term has a formal, specialized feel and appears more often in educational and linguistic contexts than in everyday conversation. Knowing the word helps explain why context may determine how an otherwise familiar spelling is spoken.

Where does heteronym come from?
The English term combines the Greek roots heteros, meaning "other" or "different," and onoma, meaning "name." This reflects the original sense of a word with the same written form as another but a different pronunciation. Related Greek-based formations include homonym, synonym, and autonym, all built on the same name-related root.
