# atoll

> English word · Noun · IPA /ˈætɒl/ · frequency rank #34,784

## Definitions
1. 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.

## 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.
