语境与语域Context & Register
语域：neutral 常见场景：描述日晷的计时原理或历史、庭院或公园中的日晷陈设、天文或科学教学场合 sundial 属于中性词，正式与非正式语境都可用；多用于介绍日晷的工作原理、历史遗迹或庭院陈设，在书面说明中比较常见。
发音与拼写Pronunciation & Spelling
The final element of sundial is pronounced /daɪl/. Mile (/maɪl/), style (/staɪl/), smile (/smaɪl/), and while (/waɪl/) match that /-aɪl/ sound, though they do not rhyme with the whole word because sundial's main stress is on the first syllable. Dial (/ˈdaɪəl/) and trial (/ˈtraɪəl/) are spelling lookalikes ending in -ial, but they have an extra schwa sound and so do not sound like the -dial in sundial as transcribed here.
