Lily is the English word for the lily flower, and most name dictionaries trace it to the Latin *lilium*, meaning "lily." The flower has long carried associations with purity and innocence in Christian symbolism, where it is often linked to the Virgin Mary. In English, the name is pronounced LIL-ee; in Germanic languages such as Dutch and Swedish it is usually LEE-lee. The spelling Lilly is also common.
As a given name Lily came into wide use in the Victorian era, when flower names were fashionable. Its best-known associations today are cultural and commercial as much as religious: the flower is a standard symbol of mourning and of Easter, and the name appears in children's literature and popular song.
