the word 'terroristic' is built upon the latin noun 'terror', which itself originates from the verb 'terrere' meaning 'to frighten, to terrify'. the suffix '-ist', entering english via latin and greek, attaches to nouns to denote a person associated with a practice or ideology, here creating 'terrorist'—one who employs systematic violence and intimidation. finally, the adjectival suffix '-ic' is appended, a common formative in english borrowed from latin and ultimately greek, to create an adjective describing anything pertaining to or characteristic of terrorists and their methods. thus, the term's literal construction follows a clear path from the concept of extreme fear, to the agent who instills it, to the descriptive quality of that agent's actions.
