List of social fraternities
Social or General Fraternities and Sororities, in the North American fraternity system, are those not associated with a particular profession or discipline; they are formed solely for the purpose of developing friendships.
Nicknames
Due to the large number of Greek organizations, and the confusion that derives from the use of combined Greek letters in predominantly English-speaking nations, many organizations may be informally better-known by their nicknames than by their letters. These nicknames usually follow certain patterns:
- An initialism based on the letters, either in Greek form or their Anglicized equivalent. For instance, Alpha Epsilon Pi as "A-E-Pi," Delta Gamma as "D-G," or Phi Gamma Delta as "FIJI"
- An invented word based on the letters, such as Pi Kappa Alpha as "Pike", Zeta Beta Tau as "Zebe", or Sigma Alpha Mu as "Sammy"
- To shorten the letters themselves, for example Sigma Nu as "SigNu" or "Sigma Phi Epsilon" as "SigEp"
- To eliminate letters, particularly when a chapter is the only one on a campus to use them: Pi Beta Phi as "Pi Phi", Alpha Delta Phi as "Alpha Delt'", or Kappa Kappa Gamma as just "Kappa" and Beta Theta Pi as "Beta". As five fraternities share the first two letters "Phi Kappa," the middle Kappa is sometimes eliminated, as "Phi Psi" for "Phi Kappa Psi" or "Phi Sig" for "Phi Kappa Sigma."
- For non-Greek lettered organizations, the use of an abbreviated word or phrase. For example, "William Penn Society" abbreviated as "Penns."
