Etymology
the adjective "jumpy" is a straightforward english formation, combining the verb "jump" with the productive adjectival suffix "-y." the verb "jump" itself is of uncertain, possibly onomatopoeic origin, emerging in the 16th century to describe a sudden springing movement. the suffix "-y," from old english "-ig," is a common means of creating descriptive adjectives from nouns and verbs, indicating a tendency or quality. therefore, "jumpy" literally means "characterized by jumping," which evolved metaphorically to describe a nervous, easily startled state where one might physically jump at slight provocations, and by extension, to describe anything that causes such a reaction.
Analysis
