What this suffix does
-winged forms compound adjectives that describe the character, span, colour, or quality of wings — and by extension the nature of flight and movement. Swift-winged, broad-winged, dark-winged, silver-winged, four-winged — each compound creates an image of a creature in flight. In English literature -winged compounds belong to the highest register: they appear in epic poetry (Homer's swift-winged Achilles), in Romantic poetry, in mythology, and in the nature writing tradition. They are among the most overtly poetic compound elements in the language — their use signals literary ambition.
