Origin & History of “pool”

Pool of water (OE) and pool ‘collective amount’ (17th c.) 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.
