billiards n.
game played on as rectangular table with ivory balls and wooden sticks, 1590s, from French billiard, originally the word for the wooden cue stick, a diminutive of Old French bille "stick of wood," from Medieval Latin billia "tree, trunk," which is possibly from Gaulish (compare Irish bile "tree trunk").
