Etymology

Origin of calorific

1675–85; < Late Latin calōrificus causing warmth, warming, equivalent to calōri- (stem of calor heat) + -ficus -fic

Explanation

Calorific is a good word for describing something that generates heat. A motorcycle race can be calorific in at least two ways: The engines get burning hot, and watching the race can make you burn with excitement. In today's diet-obsessed world, you'd be forgiven for thinking that calorific means "filled with calories." In fact, when you do something calorific you don't load up on calories; you get rid of them. Say you drink a bottle of soda and then jump on the treadmill. All those calories you just poured down your throat? You're burning them up, turning them into heat. Running is a calorific activity. And a sweaty one.
