- Semantic progression
Semantic progression, also known as 'semantic shift,' describes the evolution of
word usage — usually to the point that the modern meaning is radically different from the original usage.Examples
* demagogue - Originally meant "a popular leader". It is from the Greek "demagogos" (leader of the people), from "demos" (people) + "agogos" (leader). Now the word has strong connotations of a
politician who panders to emotions andprejudice .
* democrat - At the time of theAmerican Revolution , the term "democrat" had all the negative connotations of the modern usage of the word "demagogue". A century later, the term had shifted in meaning enough that it was viewed favorably as the name of a national political party.
* egregious - Originally described something that was remarkably good. The word is from theLatin "egregius" (outstanding) which is from e-, ex- (out of) + greg- or grex (flock). Now it means something that is remarkably bad or flagrant.
* guy - Guido (Guy) Fawkes was the alleged leader of a plot to blow up the English Houses of Parliament on5 November 1605 . The burning on5 November of a grotesqueeffigy of Fawkes, known as a "guy," led to the use of the word "guy" as a term for any "person of grotesque appearance" and then to a general reference for a man, as in "some guy called for you." In the 20th century, under the influence of American popular culture, "guy" gradually replaced "fellow," "bloke," "chap" and other such words throughout theEnglish-speaking world , and is also referred to "both" genders (i.e., "Come on you guys!" could refer to a group of men and women).From http://www.enjoywords.com/semantic_change.html
