Word Origin & History

plumb
c.1300, "lead hung on a string to show the vertical line," from O.Fr. *plombe, plomme "sounding lead," from L.L. *plumba, originally pl. of L. plumbum "lead," the metal, of unknown origin, related to Gk. molybdos "lead" (dial. bolimos), probably from an extinct Mediterranean language, perhaps Iberian.
The verb is first recorded c.1380, with sense "to immerse;" meaning "take soundings with a plumb" is first recorded 1568; fig. sense of "to get to the bottom of" is from 1599. Plumb-bob is from 1835. Adj. sense of "perpendicular, vertical" is from c.1460; the notion of "exact measurement" led to extended sense of "completely, downright" (1748), sometimes spelled plump or plunk.

plumbing definition


(Unix) Term used for shell code, so called because of the prevalence of "pipelines" that feed the output of one program to the input of another. Under Unix, user utilities can often be implemented or at least prototyped by a suitable collection of pipelines and temporary file grinding encapsulated in a shell script. This is much less effort than writing C every time, and the capability is considered one of Unix's major winning features. A few other operating systems such as IBM's VM/CMS support similar facilities.
The tee utility is specifically designed for plumbing.
