atoll means A type of island consisting of a ribbon reef that nearly or entirely surrounds a lagoon and supports, in most cases, one to many islets on the reef platform.
atoll is pronounced /ˈætɒl/.
Why “atoll” is a great word
A coral island consisting of a ring-shaped reef that encloses a central lagoon, often supporting small islets on the reef platform. From Portuguese *atol*, from Dhivehi އަތޮޅު (*atoḷu*), possibly from Prakrit *saṃtīṭha*, from Sanskrit *saṃtīrtha* ("level ford"). Unlike a “cay,” a simple sandy cap on a reef, or a “barrier reef,” which parallels a distant mainland, the atoll is a self-contained, oceanic architecture. It is the green smudge of palm islets upon a white bone-ring of coral, the impossible turquoise of the lagoon held within, and the profound silence of water a thousand fathoms deep just beyond the reef’s edge—a tenuous circle of life drawn against the abyss.
Etymology
Borrowed from Portuguese atol, from Dhivehi އަތޮޅު (atoḷu), possibly from Prakrit *𑀲𑀁𑀢𑀻𑀞 (*saṃtīṭha), from Sanskrit *संतीर्थ (*saṃtīrtha, “level ford”). The traditional etymology from Persian آبتل (âb-tal, “water-hillock”) is unlikely.
noun
