the word 'terrorism' is a modern construction built upon the ancient latin root for profound fear. the core, 'terror', originates from the latin verb terrere, meaning to frighten or terrify, which itself may trace back to a proto-indo-european root suggesting trembling or agitation. the suffix '-ism' was borrowed from greek via latin, used to form nouns indicating a distinctive practice, system, or ideology. thus, the term literally constructs the meaning "the practice or system of causing terror," a logic that directly captures its modern definition of employing violent intimidation to achieve political objectives. the word gained its specific political connotation during the reign of terror in the french revolution, where it described state policy, before evolving to its contemporary usage primarily focused on non-state actors.
