Etymology

Origin of exact

First recorded in 1525–45; late Middle English exacten (verb), from Latin exāctus (past participle of exigere “drive out, thrust out”), equivalent to ex- ex- 1 + ag(ere) “to drive” + -tus past participle suffix

Explanation

If something's exact, it's precise and completely accurate — as opposed to a guess, an estimate, or an approximation. Exact also has the meaning of taking something from someone, often money, and generally only given up with reluctance under the threat of force. The Mob might exact a shakedown from unfortunate businessmen, for example. The word comes from the Latin exactus "exact or accurate," a form of the verb exigere — meaning "to force out or demand," like the Mob demanding its money.
