Leadsman

Part of speech: noun

Pronunciation: /ˈliːdz.mən/

Definitions

1. A maritime navigator who uses a sounding line to determine water depth and guide a vessel safely through aquatic environments

Etymology: The leadsman is named after the lead, not the leading. Sounding a channel meant dropping a weighted line over the side, and the weight at its end was a block of lead, which is what gave the crewman his title. The word's origins are two separate English roots that happen to look alike: the first is the lead that the sailor swung and dropped into the water, and the second is the old sense of "lead" as guidance. The sounding line was a practical tool, marked at intervals so that the depth could be read as it was hauled back up. The word's earlier form, from Middle English, was "ledes-man," and it referred to a military commander or general, so it began on land with a sense of directing others. The "leads" part of the word is the genitive of "lead," meaning a directing or guiding, while the "man" is simply the person doing the job.
