The two Greek letters of the alphabet that the W.H.O. intentionally skip when naming the omicron variant are: Nu and Xi.
In naming the several variants of the coronavirus, the first twelve letters of the Greek alphabet have been used.
However, in naming the recent variant, the 13th and 14th letters of the Greek alphabet were skipped.
Nu was skipped because it sounds like 'new' so there might be misconceptions about it.
Xi sounds like the name of the Chinese President, so it was not used.
Finally, the 15th letter of the Greek alphabet, omicron, was used.
