Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[Obsolete French, helmsman, from Old French, from Old Italian pilota, alteration of pedota, from Medieval Greek *pēdōtēs, from Greek pēda, steering oar, pl. of pēdon, blade of an oar; see ped- in Indo-European roots.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

From Middle French pilot, pillot, from Italian piloto, from Late Latin pillottus; perhaps ultimately from Ancient Greek πηδόν (pēdon, "blade of an oar, oar") , hence also Ancient and Modern Greek πηδάλιον (pēdalion), "rudder" .

  • The actual name of the device known as a cowcatcher.

  • A definition seems to be missing: the use of 'pilot' in the sense of a trial of a completed (first version of a) product. For example: "We will be releasing this new software in June, following a pilot with selected users in May." I see this use frequently, both as a noun in the previous example and as an adjective, as in: "The pilot project was a success, we can go ahead with the release."
