Etymology

[edit]

The most common uppercase form is a variant of omicron (Ο), broken up at the side (), with the edges subsequently turned outward (, , , ). The alternative uppercase form, found in some typefaces, that looks like a larger version of lowercase ω, is from a digraph of two omicrons written close together.
