List of student organizations in North America (fraternities and sororities)
This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "List_of_student_organizations_in_North_America_(fraternities_and_sororities)".

Social or general fraternities and sororities, in the North American fraternity system, are those that do not promote a particular profession (as professional fraternities are) or discipline (such as service fraternities and sororities). Instead, their primary purposes are often stated as the development of character, literary or leadership ability, or a more simple social purpose.

Fraternity is usually understood to mean a social organization composed only of men, and sorority one of women; co-ed groups are usually called "co-ed fraternities." Traditionally these organizations have names consisting of three or occasionally two letters of the Greek alphabet, leading to their being referred to informally in various contexts as being "Greek". For the purposes of this article, national also includes international organizations, and local refers to organizations that are either composed of only one chapter, or are extremely limited in geographic and chapter roll size.

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 are often informally better-known by their nicknames, than by their Greek letters. These nicknames usually follow certain patterns:

• An initialism based on the letters, either in Greek form or their Anglicized equivalent. Examples include Alpha Epsilon Pi as "A-E-Pi," Delta Upsilon as "D-U,", Kappa Alpha Order as "KA", or Kappa Delta Rho as "KDR".
• An invented word based on the letters, such as "Teke" from Tau Kappa Epsilon, "Pike" from Pi Kappa Alpha, "Fiji" from Phi Gamma Delta, or "Sammy" from Sigma Alpha Mu.
• To shorten the names of the letters themselves, for example Psi Upsilon as "Psi U", Pi Kappa Phi as "Pi Kapp", Phi Kappa Theta as "Phi Kap", Sigma Phi Epsilon as "SigEp", or Phi Delta Theta as "Phi Delt".
• To eliminate letters: Pi Beta Phi as "Pi Phi" or Phi Kappa Tau as "Phi Tau".
• To use the dominant letter in the organization name, for example "Betas" for Beta Theta Pi, "Kappas" for Kappa Kappa Gamma, "Delts" for Delta Tau Delta, or "Thetas" for Kappa Alpha Theta.
• For non-Greek lettered organizations, the use of an abbreviated word or phrase. For example, members of the "Franklin Society" can be nicknamed "Franklins."
