英文词源

pool

pool: Pool of water [OE] and pool ‘collective amount’ [17] are distinct words in English. The former comes from a prehistoric West Germanic *pōl-, source also of German pfuhl and Dutch poel. The latter was borrowed from French poule ‘hen’, a descendant of Latin pullus ‘young chicken’ (source also of English pony, poultry, and pullet).

There was a French game called jeu de la poule, the ‘hen game’, involving throwing things at a hen – which you won as a prize if you hit it. Hence poule came to be used figuratively for ‘target’, and also for ‘that which is at stake in a game’ – source of the original meaning of English pool, ‘stake’. This evolved via ‘stake made up of players’ contributions’ to ‘collective amount’ and ‘collective resource’. Pool the snooker-like game is the same word; the game was originally played for a collective stake.
=> foal, pony, poultry, pullet

pool (n.2)

game similar to billiards, 1848, originally (1690s) a card game played for collective stakes (a "pool"), from French poule "stakes, booty, plunder," literally "hen," from Old French poille "hen, young fowl" (see foal (n.)).

Perhaps the original notion is from jeu de la poule, supposedly a game in which people threw things at a chicken and the player who hit it, won it, which speaks volumes about life in the Middle Ages. The notion behind the word, then, is "playing for money." The connection of "hen" and "stakes" is also present in Spanish polla and Walloon paie.
