“plumb-bob”


The “plumb” in “plumb-bob” comes from the fact that such tools were originally made of lead (Latin: plumbum, French: plomb). The adjective “plumb” developed by extension, as did the noun “aplomb,” from the notion of “standing upright.”

so where does the “bob” in “plumb-bob” come from?

A bob is the weight on the end of a pendulum found most commonly, but not exclusively, in pendulum clocks.

It would ‘bob’ up and down when you dropped it when it reached the length of its cord?...............
