"Phantom Words" refer to words that people believe they have heard or seen, but they do not actually exist in the language. This phenomenon often occurs when individuals misremember or misinterpret a word, leading to confusion or the creation of a term that sounds plausible but is not recognized in dictionaries. These words can arise from a variety of sources, including miscommunication, slang, or even cultural references. They highlight the fluid nature of language and how it evolves over time, as well as the role of perception in understanding and using words.
