dispatcher

Etymology

It is formed from English dispatch + -er, an agent noun from the verb.^[2][3][4] Dispatch is from Spanish despachar (“to expedite, hasten”) or Italian dispacciare, whose second element is of uncertain origin.^[3]

Earliest recorded meaning

One who dispatches, in any of the senses of the verb: 1549, in John Bale's preface to Leland's Laboryouse Journey.^[2] Etymonline dates it to the mid-16th century and Dictionary.com to 1540–50.^[3][4]

Semantic evolution

The word followed the senses of dispatch: someone who sends people or things off, or gets business done quickly.^[2][5] In North America it became the name of the railway official who sends out trains, the train dispatcher,^[2][6] and later of anyone who directs the departures of buses, trucks, planes or other vehicles.^[5][6] In computing, a dispatcher is a routine that decides the order in which tasks or devices get access to the processor.^[6] In late 18th-century gambling slang dispatchers were false dice marked so that the thrower could not lose: the Sporting Magazine has dispatches in 1796 and dispatchers in 1797, explaining that they would "dispatch" a young man's money in minutes;^[7] the OED dates this sense to 1798.^[2]
