==Etymology==
[http://nordan.daynal.org/wiki/index.php?title=English#ca._1100-1500_.09THE_MIDDLE_ENGLISH_PERIOD Middle English], from Anglo-French & [[Latin]]; Anglo-French, from Latin expertus, from past participle of experiri
*Date: [http://www.wikipedia.org/wiki/14th_Century 14th century]
==Definitions==
*1 obsolete : [[experienced]]
*2 : having, involving, or displaying special [[skill]] or [[knowledge]] derived from [[training]] or [[experience]]
==Description==
An '''expert''' is someone widely recognized as a [[reliable]] [[source]] of [[technique]] or [[skill]] whose faculty for [[judging]] or [[deciding]] rightly, justly, or [[wisely]] is accorded [[authority]] and [[status]] by their [[peers]] or the [[public]] in a specific well-distinguished domain. An expert, more generally, is a [[person]] with extensive [[knowledge]] or [[ability]] based on [[research]], [[experience]], or occupation and in a particular area of [[study]]. Experts are called in for [[advice]] on their respective subject, but they do not always agree on the particulars of a field of [[study]]. An expert can be, by [[virtue]] of credential, [[training]], [[education]], [[profession]], publication or [[experience]], believed to have special [[knowledge]] of a subject beyond that of the average person, sufficient that others may officially (and [[legally]]) rely upon the [[individual]]'s [[opinion]]. Historically, an expert was referred to as a [http://www.wikipedia.org/wiki/Sage sage] (Sophos). The [[individual]] was usually a [[profound]] thinker distinguished for [[wisdom]] and sound [[judgment]].
Experts have a prolonged or [[intense]] experience through [[practice]] and [[education]] in a particular field. In specific fields, the definition of expert is well established by [[consensus]] and therefore it is not [[necessary]] for an [[individual]] to have a [[professional]] or [[academic]] qualification for them to be accepted as an expert. In this respect, a shepherd with 50 years of experience tending flocks would be widely recognized as having complete expertise in the use and [[training]] of sheep dogs and the care of sheep. Another example from [[computer science]] is that an expert [[system]] may be taught by a [[human]] and thereafter considered an expert, often outperforming [[human beings]] at particular tasks. In [[law]], an expert [[witness]] must be recognized by [[argument]] and [[authority]].[http://en.wikipedia.org/wiki/Expert]
