jockey

Origin

The word is by origin a diminutive of jock, the Northern English or Scots colloquial equivalent of the first name John, which is also used generically for "boy" or "fellow" (compare Jack, Dick), at least since 1529. A familiar instance of the use of the word as a name is in "Jockey of Norfolk" in Shakespeare's Richard III. v. 3, 304. Equivalent to jock + -ey. In the 16th and 17th centuries the word was applied to horse-dealers, postilions, itinerant minstrels and vagabonds, and thus frequently bore the meaning of a cunning trickster, a "sharp", whence the verb to jockey, "to outwit" or "to do" a person out of something.
