Something that reduces a person's or animal's self-control, allowing them to act more freely or impulsively.
Alcohol is often considered a disinhibitor because it can make people act without their usual restraints.
Disinhibitor → It is formed from "dis-" (meaning apart or away) and "inhibere" (meaning to hold back or restrain) and "-or" (meaning one who). The word describes something or someone that removes the restraints or holds back from an action.
Think of 'dis-' meaning to remove or take away and 'inhibere' meaning to hold back — a disinhibitor is something that takes away the hold back.
