Etymology

Origin of lullaby

1550–60; equivalent to lulla, lulla ( y ), interjection used in cradlesongs ( late Middle English lullai, lulli ) + -by, as in bye-bye

Explanation

If anyone has ever sung a song to you before bedtime, trying to lull you to sleep, you can call that song a lullaby. Lullabies are usually soft and soothing tunes — more like "Twinkle, Twinkle, Little Star" than AC/DC's "Back in Black." Many lullabies are folk tunes, and most of them are simple melodies with repetitive lyrics. You might be familiar with lullabies like "Hush, Little Baby," "Rockabye Baby," and "Twinkle Twinkle Little Star," all of which have been sung for generations to sleepy children by their parents, grandparents, and babysitters. The word lullaby comes from the Middle English lullen, "to lull or soothe," and bye, as in "bye bye."
