broad-brimmed

The compound adjective 'broad-brimmed' is a transparent descriptive formation from two native English elements. 'Broad' is an ancient Germanic word, from Proto-Germanic braidaz, retaining its core sense of great width. 'Brim' originally meant the edge or margin of the sea or a river in Middle English, later extending to the projecting rim of a hat. The suffix '-ed' is added to nouns to create adjectives denoting possession of that feature. Thus, the literal construction "having a wide brim" directly and logically describes the physical attribute of a hat, with no significant semantic evolution from its component parts.

Structure: broad (wide) + brimmed (having a brim) - broad: From Old English 'brād', meaning wide, flat, extensive. A Germanic root. - brimmed: Derived from the noun 'brim' (the projecting edge of a hat) + the suffix '-med', a variant of '-ed' used to form adjectives meaning "having or provided with".
