sharp-edged

The compound adjective 'sharp-edged' is a transparent combination of two native English elements. The first element, 'sharp', descends from the Proto-Germanic skarpaz, itself from the Proto-Indo-European root (s)kerb-, meaning "to cut," which is also the source of words like 'scrape' and 'shear'. The second element, 'edged', originates from the Old English noun 'ecg' (edge, blade), derived from the Proto-Germanic agjo. The suffix '-ed' is used to form adjectives from nouns, indicating possession of the specified feature. Thus, the literal meaning "having a sharp edge" evolved naturally to describe both physical objects and, metaphorically, the incisive quality of language or perception, maintaining a clear logical link between the ancient concept of cutting and the modern abstract sense of keenness.

Structure: sharp (having a fine edge) + edged (provided with an edge) - sharp: From Old English 'scearp' (having a cutting edge, keen). Functional role: Adjective root describing the quality. - edged: From Old English 'ecg' (edge, blade) + the suffix '-ed' (having, provided with). Functional role: Adjective-forming suffix attached to a noun, creating a compound adjective.
