red-coated

The compound adjective "red-coated" is a transparent English formation. Its first element, "red," descends from the Proto-Germanic raudaz, a primary color term. The second element, "coat," entered English via Old French, denoting a tunic or outer layer. The suffix "-ed," of ancient Germanic origin, is added to nouns to create descriptive adjectives indicating possession of that noun's quality. Thus, the literal construction "having a red coat" directly conveys its modern meaning, historically and famously associated with British soldiers of the 18th and 19th centuries.

Structure: red (color) + coat (garment) + ed (adjective suffix) - red: From Old English read, of Germanic origin; related to Dutch rood and German rot. Functions as the color adjective. - coat: From Old French cote, of uncertain ultimate origin. Functions as the noun for an outer garment. - ed: From Old English -ede, -od, -ad, forming adjectives from nouns. Functions as a suffix meaning "having, wearing, or characterized by".
