the word 'terrify' is a direct borrowing from latin terrificare, which itself is a compound of terrere ('to frighten, to terrify') and the causative suffix -ficare ('to make'). the latin root terrere is of uncertain origin but may be related to the concept of trembling or shaking from fear. entering english in the late middle english period, the word retained its literal causative meaning of 'to cause fright'. over time, its usage solidified to describe the action of inducing intense, overwhelming fear, a meaning that remains closely tied to its original latin construction.

Structure: terri (frighten) + fy (make, cause to be) - terri: from latin terrere, meaning 'to frighten, to terrify'. it functions as the core root conveying the sense of fear. - fy: from latin -ficare, a verb-forming suffix meaning 'to make, to cause to be'. it functions as a causative suffix.
