40 Opulent O-Words To Optimize Your Vocabulary
The letter O is one of only a handful of letters in our alphabet whose shape hasn’t changed much throughout its entire history. We can be fairly sure that O’s earliest ancestor was a Phoenician letter, ayin, that was based on a drawing of a human eye (hence O’s circular shape) and was in turn descended from a similarly shaped Egyptian hieroglyph. In these ancient languages, however, O—or, at least, its eye-shaped ancestor—probably represented a consonant, and it took the Ancient Greeks to adopt it and use it to represent their letter omicron to transform our humble O into a vowel.
Nowadays, O is one of the most-frequently used letters of our alphabet, accounting for just over 7 percent of a standard page of text and just over 3 percent of all the words in a standard dictionary—including the 40 outstanding O words outlined here.
