Synonym discussion
Sense: adverb/1
All four adverbs intensify the degree or manner of an action or quality by linking it to fear, but they differ in tone and context. 'Frighteningly' is the most neutral — it fits both speech and writing ('frighteningly expensive'). 'Horrifyingly' is stronger, carrying a sense of shock or moral outrage ('horrifyingly violent'). 'Alarmingly' focuses on causing sudden worry, often used with statistics or trends ('alarmingly fast population growth'). 'Terribly' is the mildest and most versatile — it can mean 'very badly' or simply 'very' in informal British English. Use 'terrifyingly' for the strongest sense: when the degree or manner is so extreme that it provokes raw fear, not just concern or distaste.

Etymology
Derived from the adjective 'terrifying' — the present participle of the verb 'terrify', which comes from Latin 'terrere' meaning 'to frighten' — combined with the adverb-forming suffix '-ly'. The base verb 'terrify' entered English in the late 1500s through French, and speakers later added '-ly' to create an adverb form describing actions or qualities that cause fear to an extreme degree.
