A toy horse that children can ride on, often made of wood or other materials, or a horse used to help pull a wagon through difficult places.
The children played on the cockhorse, pretending to ride into battle.
Cockhorse → The word 'cockhorse' is formed from 'cock' (from Middle English *cok*, meaning a small horse or pony) and 'horse' (from Old English *hors*, meaning horse). The term originally referred to a child's toy horse, often used for riding or play, resembling a small horse.
Imagine a small 'cock' (a young or small horse) that children can 'ride' (like a horse) — that's why 'cockhorse' refers to a toy horse for children.
