Today's words

Boring WOTD today, but a couple from the puzzle:

gulosity /gyu-LAH-sih-tee/ - excessive appetite : greediness

Maybe this is my problem?  (I had heard of this word before.)

dewar /DEW-er; DYEW-er/ - a glass or metal container made like a vacuum bottle that is used especially for storing liquefied gases —called also Dewar flask

This, however, was a new one. I wonder if the inventor was akin to the Scotch whiskey family. I suppose this name may be a Scottish equivalent of "Smith" in popularity.
