Forms: In 1600s atollon.

Etymology: < Maldivian atoḷu, applied to the Maldive Islands, which are typical examples of this structure; perhaps related to Malayalam aḍal a sinking reef (Yule). N.E.D. (1885) gives the pronunciation as (ătǫ·l) /əˈtɒl/.

A coral island consisting of a ring-shaped reef enclosing a lagoon. Darwin's theory, now generally accepted, is that the lagoon occupies the place of a submerged island.
