Listless

“Listless” means that someone is dull or lethargic. This word originated in the days of sail. …Therefore, a vessel that has no wind or list is “listless” and slow moving.

Featured painting: This Dutch ship is

becalmed and listless. She would have been 

spiksplinter nieuw when she was new. 

Painting c. 1662 by Willem Van de Velde.
