语境与语域Context & Register
语域：mixed 常见场景：everyday descriptions of light or glow、scientific and technical writing about radiation 该词在日常语境中通常指“光辉、光彩”，语气中性；在物理学等专业领域则作为“辐射度”术语，多用于正式语体。选择时可根据句子主题判断。
发音与拼写Pronunciation & Spelling
Radiance ends in the unstressed /iəns/ sound. Audience and obedience share that final /diəns/ sound, but their stressed vowels differ, so they do not rhyme. The -iance words brilliance, defiance, reliance, and compliance only resemble the spelling: brilliance has /jəns/, while the others have /aɪəns/.
