Edginess is formed from "edge" (from Old English "ecg", meaning the boundary or sharp side of an object) and "-iness" (a suffix used to form nouns indicating a state or condition). The word "edginess" refers to the state of being sharp or tense, often in a metaphorical sense of anxiety or nervousness.
Think of the 'sharp side' ('edge') of something, which can make you feel tense or anxious — that's what edginess means.
