Definitions

1. The phenomenon where living organisms produce light through biochemical processes in their body, resulting in illumination in dark surroundings
2. The biological capability of some organisms to generate light via chemical reactions, creating visible luminescence often seen in aquatic environments
3. The natural emission of light produced by certain living creatures through chemical reactions within their cells

Etymology: Bioluminescence is a compound built from two Greek-derived halves. The first, "bio-", comes from Ancient Greek "bios", meaning "life," while the second half, "luminescence," comes from Latin "lumen," meaning "light." Neither half existed in the sense of a single scientific coinage in classical times, so the word as a whole is a modern construction assembled from classical building blocks. The "luminescence" portion carries its own history. Latin "lumen" gave rise to a suffix "-escence," formed from the Latin "-escere," which expresses the idea of beginning to be or becoming something. Adding it to "lumen" produced "luminescence," a term for light produced without the heat of burning. "Bioluminescence" then joined this to "bio-," so the word literally describes living things becoming light.
