Lei () is a garland or wreath. More loosely defined, a lei is any series of objects strung together with the intent to be worn. The most popular concept of a lei in Hawaiian culture is a wreath of flowers presented upon arriving or leaving as a symbol of affection. This concept was popularized through tourism between the Hawaiian Islands and the continental United States in the 19th and 20th centuries.
Children and sweethearts are poetically referred to as "lei" and many ancient and modern songs and chants refer to this imagery.
