Fraternities and sororities
In North America, fraternities and sororities are social organizations at colleges and universities. They are sometimes collectively referred to as Greek life. Generally, membership in a fraternity or sorority is obtained as an undergraduate student but continues thereafter for life. Some accept graduate students as well. Individual fraternities and sororities vary in organization and purpose, but most share five common elements:Secrecy
Single-sex membership
Selection of new members based on a two-part vetting and probationary process known as rushing and pledging
Ownership and occupancy of a residential property where undergraduate members live
A set of complex identification symbols that may include Greek letters, armorial achievements, ciphers, badges, grips, hand signs, passwords, flowers, and colors
