Mnemonic

You shout words into a pitch-black cave, and the whole cavern erupts with light—that's how you elucidate! Your words bounce off every wall, illuminating the whole space. The right words, spoken with conviction, make the whole hidden truth visible. Speak, and darkness vanishes.
Additional thoughts
Imagine words as beams of light; only when they fill the whole space does full elucidation occur. Partial words leave shadows—complete words reveal everything.
Quick recall
Shining words that fill the whole darkness elucidate the truth.
