Morphology

boatswain = boat + swain (semi-transparent) = boat + swain

The components 'boat' + 'swain' directly describe a boat servant, but 'swain' is archaic/rare and the modern pronunciation 'bosun' diverges from spelling, reducing learner transparency.

Etymology

Boatswain comes from two old parts: boat and swain, where swain meant 'servant' or 'young man', so it originally meant the 'boat servant' who looked after ropes and gear. That's why a boatswain today is the ship officer who cares for the ship's equipment and the crew that maintains it.
