Lei (pronounced Lay) 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.
A lei can be given to someone for a variety of reasons. Most commonly, these reasons include love, honor, or friendship for another person. Common events during which leis may be distributed include graduations, weddings, and school dances. Often the composition of a lei determine the meaning behind a lei; a lei made using a hala fruit for instance is said to be connected to love, desire, transition, and change.
A lei (nā lei is the plural in the Hawaiian language) may be composed of a pattern or series of just about anything, but most commonly consists of fresh natural foliage such as flowers, leaves, vines, fern fronds, and seeds. The most commonly used flowers are those of plumerias, tuberose, carnations, orchids, and pikake, though maile leaves, ferns, and tī leaves are extremely popular as well as traditional among hula dancers. Other types of lei may include sea or land shells, fish teeth, bones, feathers, plastic flowers, fabric, paper (including origami and monetary bills), candy, or anything that can be strung together in a series or pattern and worn as a wreath or a necklace. The Hawaiian Island of Ni‘ihau is famous for its lei made of tiny gem-like shells.
