1. sparing or moderate in eating and drinking; temperate in diet.
2. characterized by abstinence: an abstemious life.

Origin: Abstemious derives from the Latin tēmētum meaning “intoxicating drink.” It entered English in the early 1600s.

Example: “Mr. Hall was no bon vivant: he was naturally an abstemious man, indifferent to luxury; but Boultby and Helstone both liked good cookery…”
Charlotte Brontë, Shirley, 1849
