The compound adjective "yellow-eyed" is a transparent formation from two native English elements. "Yellow" descends from the Proto-Germanic gelwaz, a color term with ancient Indo-European roots seen in words like Latin helvus (pale yellow). "Eyed" employs the Old English noun ēage for the organ of sight, combined with the adjectival suffix -ed to indicate possession of a specific feature. The compound follows a straightforward descriptive pattern common in English, where a color adjective modifies a noun-derived "-ed" form to create a precise physical descriptor, primarily used in zoological and ornithological contexts to classify species.

Structure: yellow (color) + eyed (having eyes) - yellow: From Old English geolu, geolwe, of Germanic origin; related to German gelb. Denotes the color. - eyed: From Old English ēage (eye) + the suffix -ed, meaning "having" or "provided with".
