Context & Register
语域：formal 常见场景：正式告示、安全指引、医疗说明 precautionary 通常用于正式或专业语境，多出现在公告、指引或说明中，日常口语里较少见。
Pronunciation & Spelling
只有 'cautionary' (/ˈkɔʃənɛri/) 与 'precautionary' 押韵：重读元音 /ɔ/ 及后面的 /ʃənɛri/ 完全一致。'precaution' 和 'caution' 有相同的拼写和 /ˈkɔʃən/ 发音，但因词尾多了 -ary 而不构成完整押韵。'discretionary'、'stationary' 和 'revolutionary' 虽然有类似的 -tionary 拼写，但重读元音不同，所以不押韵。
