deter
UK: dɪˈtɜː(r) | US: dɪˈtɜːr
vt. to discourage or prevent someone from doing something, typically by instilling doubt or fear
vt. to hinder or impede an action or process
The word "deter" originates from Latin deterrere, combining de- (away) and terrere (to frighten). It originally meant "to frighten away" or "dissuade through fear." Over time, it broadened to include any form of discouragement or prevention, whether through fear, doubt, or practical obstacles. The logic is clear: to "deter" is to push someone or something away from an action by creating a barrier—emotional or physical.
