To use up completely; to drain entirely of strength, resources, or possibilities.

Suggests reaching absolute zero—leaving nothing left to give or use.

The story behind the word. Roman farmers used 'haurire' to describe dipping a bucket into a well to pull up water. When you did this until the well was bone dry, you had 'ex-haurire'—drawn out every single drop. The word made its way into English to signify draining resources or human vigor down to absolute zero.
