Etymology
Origin of lucidity
First recorded in 1650–60; from Latin lūciditās, equivalent to lūcid(us) lucid ( def. ) + -i- ( def. ) + -tās -ty 2 ( def. )
Explanation
A good word definition should be characterized by its lucidity, or clarity. In other words, it should be clear and easy to understand — like this one. Lucidity comes from the Latin lucidus meaning "light, bright, clear." Certainly when something is light, bright, and clear, it's ripe with the quality of lucidity. An easy-to-read textbook is characterized by lucidity. A person too can possess a quality of lucidity, one that would allow her to express ideas as clearly as possible.
