What does lucency mean?
Lucency is a rare noun denoting the quality of shining or radiating light. It can describe the soft glow of the moon, the luminous sheen of a pearl, or the radiant quality of another surface, without necessarily implying intense brightness. The word is especially characteristic of formal and literary prose, where it can lend elegance to descriptions of natural or reflected light. Lucency should not be confused with lucidity, which normally refers to clarity of thought, expression, or style. Although uncommon in contemporary English, lucency is useful for precise, evocative writing about luminosity as a perceptible quality. The more familiar words luminosity and radiance cover much of its meaning, but lucency has a more distinctly poetic and visual tone.

The regular plural is rarely used because the headword itself is uncommon.
