Learner notes
Memory Tip
随机：random（乱）加上名词后缀-ness，事情乱得没规律，就是随机性。
Context & Register
语域：neutral 常见场景：概率统计课程、日常交流、学术写作 randomness 在日常口语和学术写作中都较常见，整体属于中性词；在概率统计或物理学语境中多作术语使用，正式感稍强，而在日常谈论“偶然、无规律”时语气更轻松。选择时可随语境自然调整，不必刻意区分正式或非正式。
Grammar Note
复数形式 randomnesses 较少见，多用于数学或技术语境中表示不同类型的随机情况。
Pronunciation & Spelling
这六个词都以拼写 -ness 结尾，且词尾非重读的 /nəs/ 音相同。但它们都不与 randomness /ˈrændəmnəs/ 完全押韵，因为重读音节及其后的音不同。注意勿看拼写想当然：business 常被误读成 /ˈbɪzɪnəs/，实际是 /ˈbɪznəs/；randomness 的重音在第一个音节，末尾 -ness 是非重读的。
