Homophones are words that sound the same but have different meanings and often different spellings. For example, the words pair (a set of two) and pear (a type of fruit) are homophones. They can create confusion in writing but can be fun to play with in language. Understanding homophones is important for effective communication. Misusing them can lead to misunderstandings. For instance, using their (belonging to them) instead of there (a place) can change the meaning of a sentence. Learning homophones helps improve both writing and speaking skills.
