Learner notes
Memory Tip
o' 像圆形钟面，o'clock 就是“按钟表报出的点钟”，看到 o' 就想起钟表圆盘。
Context & Register
语域：neutral 常见场景：telling the time、everyday schedules o'clock 通常用于口语和一般书面语中表示整点时间；正式文体中也可使用，但若需要更严谨的钟点表达，有时会省略 o'clock。日常对话和安排时间时最常用。
Grammar Note
只用于数字1到12后面表示整点；数字时间或带a.m./p.m.时一般不用。
Pronunciation & Spelling
这些词都以重读的 /ɑk/ 押韵（按音标 /əˈklɑk/）。注意 o'clock 中的 o 读 /ə/，不读 /oʊ/；lock 和 luck 拼写相似但发音不同（/lɑk/ vs /lʌk/）。
