dongle

Unknown. Likely a descendant of dangle, reflecting that electronic accessories such as computer peripherals often are plugged in via a flexible cable (although wirelessness is also often relevant). Claims that the word comes from a man named "Don Gall" were made up by an advertisement. First usage 1980-1985.

   • 1997 April 1, David McCandless, “Warez Wars”, in Wired‎, →ISSN:

     Take the dongle, for example. It is the summit of copy protection, an explicit melding of software and hardware. Without the right hardware key—the dongle—plugged into the machine's parallel port, the software won't run.
