In addition to its use as an alphabetic letter, omicron is occasionally used in technical notation,[citation needed] but its use is limited since both upper case and lower case (Ο ο) are indistinguishable from the Latin letter "o" (O o) and difficult to distinguish from the Arabic numeral"zero" (0).
In the earliest Greek inscriptions, only five vowel letters A E I O Y were used. Vowel length was undifferentiated, with O representing both the short vowel /o/ and the long vowels /o:/ and /ɔː/.(p 19) Later, in classical Attic Greek orthography, the three vowels were represented differently, with O representing short /o/, the new letter Ω represen...

This timeline of the SARS-CoV-2 Omicron variant (November 2021 – February 2022) is a dynamic list, and as such may never satisfy criteria of completeness. Some events may only be fully understood and/or discovered in retrospect. The extensive mutations of its spike proteins make for the Omicron variant.
