Conker is the name used in Britain, Ireland and some former British colonies for the nuts of the Common Horse-chestnut tree, when used in a game traditionally played by children, Conkers. The name comes from the nineteenth-century dialectal word conker meaning snail-shell (related to French conque meaning a conch), as the game was originally played using snail shells. The name may also be influenced by the verb conquer, as the game was also called conquerors.
