Deterrent 一词源自拉丁语 deterrere （使害怕、使气馁），19世纪初进入英语后既作形容词表示“威慑的、吓阻的、遏制的”，也作名词表示“威慑力量、遏制因素、制止物”，强调使人害怕事情后果而不敢做某事，比如：
Undercover police swooped on three houses in the city this morning. Hopefully, that will have a deterrent effect on drug syndicates in the future.
Tougher prison sentences may act as a deterrent to other would-be offenders, especially those who regularly flout the law.
值得注意的是，deter 是 deterrent 的动词形式，主要表示“制止、阻止、威慑、使不敢”，强调使人明白困难程度或者不良后果来使人放弃做某事，但其威慑强度要小于 deterrent ，比如：
