The compound adjective "white-crowned" is a modern English formation, combining two native concepts. "White" descends from the Proto-Germanic hwītaz, a fundamental color term. "Crown" entered English via French from Latin corōna, originally denoting a garland or wreath as a mark of honor, which semantically narrowed to mean the top of the head. The suffix "-ed" is added to the noun "crown" to create a participial adjective meaning 'furnished with a crown'. The term's logic is transparently descriptive, literally "having a crown that is white," and is used primarily in ornithology to name bird species distinguished by this specific plumage feature, such as the White-crowned Sparrow.

Structure: white (color) + crown (top of the head) + ed (adjective suffix) white: From Old English hwīt, meaning the color white; the color sense. crown: From Anglo-French coroune, Old French corone, from Latin corōna 'garland, wreath, crown'; the head or top part. ed: A suffix forming adjectives from nouns, meaning 'having or provided with'.
