I thought as I came across notable words from Wordnik's Word of the Day service, I'd post them here. Here's today's.
The Wordnik Word of the Day for October 11, 2010 is
(noun) A green hand on board a whaler, usually placed in the waist of the vessel until qualified for more responsible duties.
(noun) On a naval vessel, formerly, one of a class of old men who have been disabled or grown gray without rising in the service.
'Waister' is named for the 'waist' or central part of the ship, where new seamen were set to work as there was little to do beyond hauling on ropes or swabbing the deck.
"They could not be got upon deck in the night, or if by dint of the rope's-end they were at length routed out of their hammocks, they immediately developed the worst symptoms of the 'waister' -- seasickness and fear of that which is high."
