Etymology
The verb "deter" originates from the mid-16th century Latin verb deterrēre, which is a compound of the intensive prefix de- and the verb terrēre, meaning "to frighten." The literal sense is thus "to frighten away" or "to scare off." This core meaning of using fear to drive something away evolved logically into the modern abstract sense of discouraging or preventing an action by making its negative consequences vividly apparent. The semantic journey is direct: from the physical act of scaring off a threat to the psychological act of discouraging a planned behavior through the threat of unpleasant results.
