Misnomers are words or phrases that suggest a meaning that is a known falsehood. These often occur when something has already been named, but is later proven to be different in nature. For example, the term “shooting-stars” is a misnomer as it is well-known that shooting-stars are actually meteors, not stars. Similarly, the Koala bear is quite unrelated to bears, despite looking and acting much like bears. A misnomer is similar to the concept of an oxymoron, a figure of speech containing contradictory elements. Very rarely, a phrase or word can be both a misnomer and an oxymoron, such as the phrases “wireless cable” and “synthetic natural gas”.
