What does the term 'homophones' refer to?

The term 'homophones' refers specifically to words that sound the same but have different meanings. This means that although these words may be pronounced identically, they can differ in both spelling and meaning. A common example is "two," "to," and "too," which all sound the same but refer to different concepts. Understanding homophones is essential for effective communication, as using the wrong word can lead to misunderstandings despite the correct pronunciation. The other options focus on different aspects of word relationships, such as spelling similarities or confusion, which do not accurately define homophones.
