Sense: noun/1
Fear is the broadest and mildest of these words, covering everything from a slight worry to a strong fright. Terror sits at the extreme end — it describes an overwhelming, paralysing fear that strikes suddenly, often in response to an immediate threat. Horror adds an element of disgust or moral shock; you feel horror at something cruel or violent, not just dangerous. Dread points forward in time: it is a deep, heavy fear of something bad that has not yet happened but feels inevitable. Panic is a sudden, uncontrolled fear that spreads quickly and makes people act without thinking. For example: you might feel fear before an exam, but terror when a car swerves toward you. A soldier feels dread before a battle, panic when the attack comes, and horror at the destruction left behind.

Etymology
Terror entered English in the 14th century from Old French 'terreur', which came from Latin 'terror' meaning 'great fear, dread, or alarm'. The Latin noun was formed from the verb 'terrēre' (to frighten). The word's political meaning — the use of violence to intimidate a population — became prominent during the French Revolution's 'Reign of Terror' (1793–1794), when the revolutionary government used harsh measures against its opponents.
