The Dickson Baseball Dictionary cites William Henry Nugent's work asserting that it was derived from the fancy, a term from England referring to the fans of a specific hobby or sport from the early 18th Century to the 19th, especially to the followers of boxing.[1] According to that theory, it was originally shortened to fance then just to the homonym fans. Merriam-Webster, the Oxford dictionary and other sources define it as a shortened version of the word fanatic. The word first become popular in reference to baseball enthusiasts. (Fanatic itself, introduced into English around 1550, means "marked by excessive enthusiasm and often intense uncritical devotion". It comes from the Modern Latin fanaticus, meaning "insanely but divinely inspired". The word originally pertained to a temple or sacred place [Latin fanum, poetic English fane]. The modern sense of "extremely zealous" dates from around 1647; the use of fanatic as a noun dates from 1650.) However, the term "fancy" for an intense liking of something, while being of a different etymology, coincidentally carries a less intense but somewhat similar connotation to "fanatic". The word emerged as an Americanism around 1889.
Supporter is a synonym to "fan" that predates the latter term and as such is still commonly used in British English, especially to denote fans of sports teams. However, the term "fan" has become popular throughout the English-speaking world, including the United Kingdom. The term supporter is also used in a political sense in the United States, to a fan of a politician, a political party, and a controversial issue.
Characteristics[edit source | editbeta]

Fans usually have a strong enough interest that some changes in their lifestyles are made to accommodate devotion to the focal object. Fans have a desire for external involvement – they are motivated to demonstrate their involvement with the area of interest through certain behaviors (attending conventions, posting online, displaying team banners outside their homes, etc.). Fans often have a "wish to acquire" material objects related to the area of interest, such as a baseball hit by a famous slugger or a used guitar pick from their musical hero. As well, some fans have a desire for social interaction with other fans. This again may take many forms, from casual conversation, e-mail, chat rooms, and electronic mailing lists to regular face-to-face meetings such as fan club meetings and organized conventions.
There are several groups of fans that can be differentiated by the intensity level of their level of involvement or interest in the hobby (level of fanaticism)[2] The likelihood for a subject of interest to be elevated to the level of fandom appears to be dictated by its complexity. Complexity allows further involvement of fans for a longer period of time because of the time needed to work the subject of interest 'out.' It also contributes to a greater sense of belonging because of the mental effort invested in the subject
