Lucid
Lucid 是一个多义词，但其核心含义都与“光”和“清晰”有关。
- 语言/思维: 指表达简洁明了，逻辑清晰，容易理解（如 a lucid explanation）。
- 意识状态: 指神志清醒，特别是在生病或神志不清的间隙（如 a lucid interval）。
- 物理属性: 指透明的、清澈的或发光的。

- luc-: 词根源自拉丁语 lux 或 lucis，意为“光”。
- -id: 形容词后缀，表示某种性质或状态。
- 同根词: lucent (发亮的), lucidly (清晰地), lucidity (清澈，明了)。
在心理学中，lucid dream（清醒梦）是一个常用术语，指人在做梦时知道自己在做梦。
- 名词形式: lucidity

记住词根 luc- 代表“光”。“清晰”就像光照进黑暗，让一切都变得透明（lucid）易见。
