Scottish National Dictionary (1700–)
CAPEY-DYKEY, CAPPIE-, n. comb. A boys' game played with marbles, which were placed in a cap at the foot of a wall or “dyke” (Ags.1 1938, cappie-); also a game played with any kind of bouncing ball: “the player stands in front of a flattish wall or ‘dyke' and throws the ball obliquely to the ground so that it will rebound from this to the wall and thence in a parabola back to the player's hands, so that he catches it or ‘capes' it. If there is a pavement in front of the wall, a marble can be used” (Ags.17 1938). [′kep-′dəiki, ′kɑp-]
