古英語のsceotan「投げる、撃つ」から、原ゲルマン語*skeutanan「投げる、撃つ」から、語源的にはPIE*skeud「投げる、撃つ」から、語源的にはsheet「シート」「ショット」「シャット」から。
O, 'tis cash makes such crowds to the gin shops roam,
And 'tis cash often causes a rumpus at home ;
'Tis when short of cash people oft shoot the moon ;
And 'tis cash always keeps our pipes in tune.
Cash! cash! &c.
