‘威慑’ (wēi shè) is a noun meaning ‘deterrence’ or ‘intimidation’—the act of discouraging unwanted behavior through the threat of force, power, or consequences. The first character 威 (wēi) means ‘power,’ ‘authority,’ or ‘menace,’ while the second 慑 (shè) means ‘to frighten’ or ‘to subdue.’ Together, they form a formal, slightly literary term emphasizing psychological influence rather than physical action: it’s about making others hesitate or back down by projecting strength or resolve.

This word appears frequently in political, military, legal, and even ecological contexts—for example, describing how predators use size or displays to deter rivals or prey, or how governments impose sanctions to deter aggression. It carries a strong connotation of calculated, strategic influence; it’s not casual fear, but purposeful, often institutionalized pressure designed to prevent undesirable outcomes before they occur.
