From Middle French pilot, pillot, from Italian pilota, piloto, older also pedotta, pedot(t)o (the form in pil- is probably influenced by pileggiare (“to sail, navigate”)); ultimately from unattested Medieval Greek *πηδώτης (*pēdṓtēs, “helmsman”), from Ancient Greek πηδόν (pēdón, “blade of an oar, oar”), hence also Ancient and Modern Greek πηδάλιον (pēdálion, “rudder”).

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
