Intense feelings of fear or extreme fright; or things that cause such fear.
From Old French 'terreur,' derived from Latin 'terror,' a noun form of 'terrere' meaning 'to frighten.' The root may connect to meanings of 'trembling' or 'being shaken.'
The word 'terror' used to be even stronger than it sounds—it literally relates to the trembling and shaking your body does when you're absolutely petrified!
