Greek alphabet

=== Use by student fraternities and sororities ===
In North America, many college [[Fraternities and sororities in North America|fraternities and sororities]] are named with combinations of Greek letters, and are hence also known as "Greek letter organizations".{{sfn|Winterer|2010|page=377}} This naming tradition was initiated by the foundation of the [[Phi Beta Kappa Society]] at the [[College of William and Mary]] in 1776.{{sfn|Winterer|2010|page=377}} The name of this fraternal organization is an acronym for the ancient Greek phrase Φιλοσοφία Βίου Κυβερνήτης (''Philosophia Biou Kybernētēs''), which means "Love of wisdom, the guide of life" and serves as the organization's motto.{{sfn|Winterer|2010|page=377}} Sometimes early fraternal organizations were known by their Greek letter names because the mottos that these names stood for were secret and revealed only to members of the fraternity.{{sfn|Winterer|2010|page=377}}

Different chapters within the same fraternity are almost always (with a handful of exceptions) designated using Greek letters as serial numbers. The founding chapter of each respective organization is its A chapter. As an organization expands, it establishes a B chapter, a Γ chapter, and so on and so forth. In an organization that expands to more than 24 chapters, the chapter after Ω chapter is AA chapter, followed by AB chapter, etc. Each of these is still a "chapter Letter", albeit a double-digit letter just as 10 through 99 are double-digit numbers. The [[Latin alphabet|Roman alphabet]] has a similar extended form with such double-digit letters when necessary, but it is used for columns in a table or chart rather than chapters of an organization.{{citation needed|date=January 2020}}
