Etymology

The word "startlingly" derives from the verb "startle," which originated in Middle English as "stertlen," meaning "to move suddenly" or "to leap up." This traces back to Old English "styrtan," meaning "to jump up." The suffix "-ing" forms the present participle, and "-ly" converts it into an adverb. The progression reflects a shift from physical movement ("leap") to emotional reaction ("shock"), emphasizing suddenness and intensity.
