The information on this page is ✔ fact-checked.

O, or o, is the fifteenth letter in the English alphabet, coming after N and before P. As a vowel, ‘O’ is pronounced with a rounded mouth shape and produces a distinct sound commonly heard in words like ‘orange’ or ‘ocean.’ In mathematics, ‘O’ represents the origin point (0,0) in the Cartesian coordinate system, essential for graph plotting and geometric analysis. ‘O’ is used in computer science to symbolize complexity in algorithm analysis and denote the order of magnitude or “big O notation” for evaluating algorithm efficiency. In everyday language, ‘O’ is often used in expressions conveying surprise, such as “Oh my goodness!” or “Oh, wow!”

The letter ‘O’ has a fascinating history that spans centuries and civilizations. Its origins can be traced back to the ancient Phoenician alphabet, where it likely represented an eye or a circle, reflected in its original name, “ayin.” This circular symbol persisted as it passed through various cultures, with the Greeks adopting it as “omicron,” meaning “small O.” The Romans later borrowed the Greek letter and adapted it into the rounded form we recognize today. Throughout its evolution, ‘O’ has retained its circular shape, symbolizing unity, wholeness, and completeness in various contexts. This journey underscores the enduring significance of ‘O’ as both a linguistic and symbolic element in human communication.
