NLN NEX Reading Comprehension & Vocabulary Strategies Practice Test

Lucid is about clarity and ease of understanding. When something is lucid, it’s expressed in a way that’s easy to follow and free from confusion. The word comes from a root meaning light, which helps you remember that a lucid explanation shines with clarity.

So the closest meaning is clear. The other options miss the idea: unclear is the opposite of lucid, repetitive has to do with repetition rather than how easy something is to grasp, and brilliant refers to brightness or sharp intellect but doesn’t inherently convey straightforward understandability.
