Our generated misspelling index lists 5 likely wrong-spelling variants for atoll, with forms such as "aotll", "atlol", and "atol". Every one of these variants traces to a single-character edit -- an added or dropped letter, a swapped consonant, or a vowel swap -- the kind of slip a spell-checker is built to catch. It also participates in 12 confusable-pair relationships, "atom", "atop", "AWOL", and more, a pairing that trips writers up because the two words share enough sound or shape to blur together.

Etymologically, the entry records: 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. The correct English form is atoll, spelled A-T-O-L-L.
