Etymology

Origin of prohibitive

First recorded in 1400–50; from Medieval Latin prohibitīvus; see origin at prohibit, -ive

Explanation

That expensive Ferrari in the showroom? You may want it, but its price is prohibitive — which means the price is discouragingly high and likely to deter you from buying. Prohibitive originally referred to something (often a law) that prohibits or forbids something, but it came to mean conditions (often prices or taxes) so high or great they restrict or prevent something: "To some, the cost of child care is prohibitive." The stress is on the second syllable, just like the verb: pro-HIB-i-tive. If it's a matter of expense, a synonym is exorbitant.
