lullaby
UK: ˈlʌləbaɪ | US: ˈlʌləbaɪ
n. a soothing song sung to lull a child to sleep
n. (figuratively) something that causes a sense of calm or relaxation
The word "lullaby" combines "lull," derived from Middle English lullen (to soothe or quiet), with the archaic term "bye" (a variant of "goodbye"), suggesting a song to lull a child "to sleep" or "into calm." The connecting "a" blends the two parts smoothly. Over time, "bye" evolved into "-by," losing its literal farewell meaning but retaining the soothing connotation. The word reflects a gentle, rhythmic sound pattern, mirroring its purpose.
