Etymology
The word "deterrent" is built from the Latin verb deterrēre, which itself is a compound of the prefix de- ("away") and the verb terrēre ("to frighten"). The literal meaning is thus "to frighten away." The suffix -ent was added to form the present participle, creating an adjective meaning "frightening away." This concrete sense of scaring something off evolved into the modern, more abstract meaning of something that discourages action by making its consequences seem severe or unpleasant. The logic remains intact: a deterrent works by instilling enough fear or apprehension to turn someone away from a course of action.
Analysis

- de: Latin origin, a prefix meaning "away, off, down, completely."
- terr: Latin origin, from the verb terrēre, meaning "to frighten, to terrify."
- ent: Latin origin, the suffix -ent- (present participle ending of verbs), forming adjectives meaning "doing or being something" and nouns meaning "one who does or is something."
