To explain something very clearly, especially something confusing or difficult. It often suggests adding detail or examples to make an idea easier to understand.
From Latin 'elucidare' meaning 'to make clear,' from 'e-' (out) + 'lucidus' (clear, bright), from 'lux' (light). Originally, it meant to shed light on something. English kept that metaphor of turning on the light in someone’s mind.
When you 'elucidate,' you’re metaphorically turning on the lights—'lucid' means bright or clear. Teaching is full of light words: 'illustrate,' 'illuminate,' 'clarify.' Your brain naturally treats understanding as a kind of seeing.
