词源

From Middle English plommet (“ball of lead, plumb of a bob-line”), recorded since 1382, from Old French plommet or plomet, the diminutive of plom, plum (“lead, sounding lead”), from Latin plumbum (“lead”). The verb is first recorded in 1626, originally meaning “to fathom, take soundings", from the noun.
