‘夕阳’ literally combines 夕 (xī), meaning ‘evening’ or ‘dusk’, and 阳 (yáng), meaning ‘sun’ or ‘sunlight’. Together, they form a poetic and commonly used noun meaning ‘sunset’ — the sun as it descends below the horizon in the evening. Unlike the more neutral term 日落 (rìluò), 夕阳 carries warm, gentle, and often nostalgic or aesthetic connotations, frequently appearing in literature, photography, and everyday descriptions of evening light.

The word is almost always used as a noun and appears in phrases like 夕阳西下 (the sunset descends westward) or 美丽的夕阳 (a beautiful sunset). It’s rarely used alone as a verb or modifier without additional context. While it can appear in compound nouns (e.g., 夕阳红 — ‘sunset red’, metaphorically referring to vitality in old age), its core meaning remains tied to the visual and temporal moment of sunset.
