Nectar is derived from the Greek word νεκταρ, the fabled drink of eternal life. Some derive the word from νε- or νη- "not" plus κτα- or κτεν- "kill", meaning "unkillable" or "overcoming death," thus "immortal." The word is thought to be derived from the Indo-European form ṇmṛtós,"un-dying."

Nectar is a sugar-rich liquid produced by plants.

Honey is produced by bees who have collected nectar or honeydew. Honey is a sweet and viscous substance made by several bees, the best-known of which are honey bees. Honey is made and stored to nourish bee colonies. Bees produce honey by gathering and then refining the sugary secretions of plants (primarily floral nectar).

Honey use and production has a long and varied history, with its beginnings in prehistoric times. Several cave paintings in Cuevas de la Araña in Spain depict humans foraging for honey at least 8,000 years ago.

Over its history as a food, the main uses of honey are in cooking, baking, desserts, as a spread on bread, as an addition to various beverages such as tea, and as a sweetener in some commercial beverages.

In ancient Greek myths, ambrosia, the food or drink of the Greek gods, is often depicted as conferring longevity or immortality upon whoever consumed it. It was brought to the gods in Olympus by doves and served either by Hebe or by Ganymede at the heavenly feast.
