A homophone is a word that sounds the same as another word but has a different meaning and often a different spelling. For example, the words pair (a set of two) and pear (a type of fruit) are homophones. They can create confusion in writing and speech, especially for those learning the language. Homophones are common in English and can be found in various contexts. They are often used in puns and wordplay, adding humor to language. Understanding homophones is important for effective communication and can enhance both writing and speaking skills.
