语源
Middle English (as a noun denoting a horse's gallop): from Old Northern French walop (noun), waloper (verb), perhaps from a Germanic phrase meaning 'run well', from the bases of well and leap. Compare with gallop. From 'gallop' the senses 'bubbling noise of a boiling liquid' and then 'sound of a clumsy movement' arose, leading to the current senses
