Usage

What does phenomenon mean? Phenomenon most generally refers to an observable occurrence or circumstance. For example, a hurricane is a kind of weather phenomenon. Phenomenon is also commonly used to refer to an extraordinary event or something that becomes the subject of widespread interest and attention, as in The movie has become a worldwide phenomenon. Sometimes, phenomenon refers to a person with an extraordinary talent or ability, especially a relatively young person who is considered a prodigy. The word phenom (a shortened form of phenomenon) is commonly used to mean the same thing, as in She became an internationally known chess phenom when she was just 14 years old. The plural of phenomenon is phenomena. The adjective phenomenal is most commonly used to mean highly extraordinary or exceptional, as in It was a phenomenal display of skill. It can also be used more generally to mean relating to phenomena in some way, as in My philosophy paper deals with the phenomenal qualities of existence. Example: Halley’s comet is a phenomenon that occurs every 76 years.

Etymology

Origin of phenomenon

First recorded in 1580–90; from Late Latin phaenomenon, from Greek phainómenon “appearance,” noun use of neuter of phainómenos, present participle of phaínesthai “to appear, become visible,” passive of phaínein “to show, bring to light, make known”

Explanation

A phenomenon is an extraordinary occurrence or circumstance. In the 1950s, rock-n-roll was considered a new cultural phenomenon, while today we think of crop circles as a mysterious phenomenon. Like many words with Greek roots, phenomenon started out as a science term. Scientists used it (and still do) to describe any event or fact that could be observed, amazing or not. An earthquake, for example, was a phenomenon, because you could see it (and hear it and feel it). Phenomenon is an example of a word having a specific meaning for one group of people that gets changed when used by the general public.
