1550s, from Latin nectar, from Greek nektar, name of the drink of the gods, which is said to be a compound of nek- "death" (see necro-) + -tar "overcoming," from PIE *tere- "to cross over, pass through, overcome." Meaning "sweet liquid in flowers" first recorded c.1600.
sweet, viscous secretion from the nectaries, or glands, in plant blossoms, stems, and leaves. It attracts fruit-eating bats, hummingbirds, and insects, who aid in effecting pollination by transferring from plant to plant the pollen that clings to their bodies. Nectar is the raw material used by the honeybee to produce honey. Mainly a watery solution of the sugars fructose, glucose, and sucrose, it also contains traces of proteins, salts, acids, and essential oils. Sugar content varies from 3 to 80 percent, depending upon such factors as flower species and soil and air conditions. Honeybees gather nectar mainly from the blossoms and rarely gather nectars having less than 15 percent sugar content.
