Etymology
The compound adjective 'elbow-length' is a transparent descriptive formation from two native English elements. 'Elbow' originates from the Old English term for the prominent bending joint of the arm, a concept central to its identifying function. 'Length' derives from the ancient Germanic root for 'long', evolving into a standard noun denoting linear measurement. Combined, they follow a straightforward Germanic compounding pattern, where 'elbow' specifies the anatomical reference point and 'length' specifies the dimension, creating a precise term for garments extending precisely to that joint. This logical construction makes the modern meaning immediately apparent from its constituent parts.
Analysis
elbow: From Old English elnboga, a compound of eln (forearm) and boga (bow, bend). It denotes the joint of the arm. length: From Old English lengþu, derived from the root lang (long) + the noun-forming suffix -þu (-th), indicating a measure or degree.
