From Latin *plumbum* meaning 'lead'. Originally referred to using a lead weight to measure depth or verticality, hence the various meanings related to measurement, verticality, and getting to the bottom of something.
Historically, 'plumb' was used to directly mean 'lead', reflecting the use of lead weights in construction and navigation. Over time, the meaning shifted to describe verticality and exploration.
