Primarily means honeycomb—the wax structure bees build to store honey. Homer and classical authors reference it alongside honey as a precious substance. The Septuagint uses it in Proverbs' description of pleasant words ('honeycomb'). Ancient medicine employed honeycomb for treatments. Metaphorically it represents sweetness and pleasure: poets call books of poems a κηρίον, and moralists speak of desire's honeycomb. One medical usage describes a skin condition resembling honeycomb structure. The diminutive form of κηρός (wax) captures both the wax cells and their sweet contents—inseparable in ancient experience.
