The Greek letters Eta and Iota from the 2020 season will be retired as well, which is significant since before this year, the WMO made it very clear that it would not ever retire Greek names.

As the first intercollegiate Greek-letter organization founded for Black men in the United States, it began in December of 1906, with the Iota chapter coming on March 10, 1941, on the MBC campus.

The entire Greek alphabet was banned from hurricane name usage after the record 2020 season. ... Iota, 2020 (from the Greek alphabet) Ida, 2021 "F" is the second-most retired letter.
