red-headed

The compound adjective "red-headed" is a transparent and relatively modern English formation. Its first element, "red," traces back to the Proto-Germanic raudaz, which itself descends from the Proto-Indo-European root h₁rewdʰ-, meaning "red" or "ruddy." The second element, "head," originates from Proto-Germanic haubudą, from the PIE root kaput-, meaning "head." The suffix "-ed" is a native English adjectival marker. The word's logic is entirely literal, combining these elements to denote the possession of a red-colored head, most commonly applied to people with red hair, showcasing a straightforward descriptive compounding process in English.
