Selected source glosses provide context, not a complete modern definition inventory

1. From French poule (“collective stakes in a game”). The French word "poule" in this context is an abbreviation of "poulain, pouliche" (foal, filly), and referred to races with female horses under 3 years old. It then became used by punters to designate bets on that race, and started to be used from the racetrack to the stadiums. 2. The OED suggests that this may be a transferred use of poule (“hen”), which has been explained anecdotally as deriving from an old informal betting game in France - 'jeu de poule' - Game of Chicken (or Hen, literally) in which poule became synonymous with the combined money pot claimed by the winner.

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.
