Origin & History of “plumb”
Plumb comes via Old French *plombe from Latin plumbum ‘lead’, a word of uncertain origin. Of its modern English uses, the verbal ‘sound the depths’ comes from the use of a line weighted with lead (a plumb line) to measure the depth of water and the adverbial ‘exactly’ from the use of a similar line to determine verticality. Related words in English include aplomb; plumber (14th c.) (originally simply a ‘worker in lead’, but eventually, since water pipes were once made of lead, a ‘pipe-layer’); plummet (14th c.) (a diminutive form coined in Old French); and plunge (14th c.) (from the vulgar Latin derivative *plumbicāre ‘sound with a plumb’).
