This post was triggered by the misspelling of the word plumber in the following passage:
Your plummer can be as creative or more than your favorite rock star or painter… What happens in his head when he needs to find a way to solve your unique sink problem is the same process that takes place in a musician’s head…
The b in plumber derives from the fact that, until fairly recently, water pipes were manufactured of lead.
The symbol for lead in the Periodic Table of Elements is Pb. The symbol derives from the Latin word for lead: plumbum.
Around 1100, a “plumber” was a worker in any sort of lead. In the 19th century the word acquired the meaning “workman who installs pipes and fittings.” The Nixon administration, concerned about information “leaks,” created a special investigative unit called the Plumbers.
A “plumb line” (also called a plumb-bob or a plummet) is a piece of lead hung on a string. Builders use plumb lines to gauge a vertical line.
As a verb, plumb has various meanings. To “plumb the depths” is to measure the depth of water by dropping a weighted line of a known length. Figuratively it means to experience something deeply. The writer plumbed the depths of despair. To plumb a chimney or other object under construction means to adjust or test it to be sure it’s straight.
Three other words that derive from the Latin word for lead are plummet, plunge, and aplomb.
Besides being a synonym for a plumb line, plummet can be used as a verb. One sense is “to fathom, to take soundings.” Its more common use is with the meaning “to fall rapidly.” Plummet is a good word to describe a precipitate and heavy fall.

A fireman and a policeman held the ends of a horse blanket to try to catch the next falling girl, but the blanket split in half as the body plummeted right through and hit the pavement.
The verb plunge comes from Vulgar Latin plumbicare, “to heave the lead.” Like plummet, the word suggests a heavy weight falling in a straight direction or forceful movement into something or in a downward direction, often into water. The expression “to take the plunge” means “to commit oneself.” The fashion term “plunging neckline” is documented from 1949.

The noun aplomb means “confidence.” The connection to the lead/plumb line idea is that a confident, assured person stands up straight.
By September 10, 2001, Rudolph Giuliani seemed to have worn out his welcome as Mayor of New York, but the sorrier aspects of his two terms of office were all but wiped from collective memory by his aplomb amidst the chaos of 9/11.
