In England, conkers are the shiny brown seeds of the horse chestnut tree. They are traditionally used in a popular children's game called "conkers," where each player threads a conker onto a string and takes turns striking their opponent's conker until one breaks. The game is typically played in autumn when the conkers fall from the trees. The name "conker" may come from a dialect word meaning "knock out," or it could be related to the French word for "shell" or the verb "conquer," reflecting the game’s competitive nature. Conkers are considered a nostalgic part of childhood in England and are collected from horse chestnut trees found in parks and gardens.
