Island Ring is a term used to describe a geographical feature consisting of a circular group of islands. The two words that make up this term are LEI (3 letters) and ATOLL (5 letters). LEI is a Hawaiian word meaning 'GARLAND' or 'WREATH' and is often used to refer to a necklace made of flowers, shells, or feathers. An ATOLL is a ring-shaped coral reef, island, or chain of islands formed by coral growth. Together, these two words form the term Island Ring, which describes a circular group of islands.
