A homograph is a word that is spelled the same as another word but has a different meaning and often a different pronunciation. For example, the word "lead" can refer to a type of metal or the act of guiding someone. Homographs can create confusion in language, especially in written form, where context is essential for understanding. These words are part of a broader category called homonyms, which also includes homophones—words that sound the same but have different meanings. Understanding homographs is important for effective communication, as it helps clarify meaning in both spoken and written language.
