cobble: Cobble as in cobblestone [15] and cobble ‘mend’ [15] are two distinct words. The former was derived from cob ‘rounded lump’, with the diminutive suffix -le. The earliest evidence of it is in the compound cobblestone, and it is not recorded on its own until about 1600. The verb cobble is a back-formation from cobbler ‘shoemaker’ [14], of unknown origin. The derivative cobblers ‘nonsense’ [20] is short for cobbler’s awls, rhyming slang for ‘balls’. => cob[cobble etymology, cobble origin, 英语词源]
