College (Latin collegium) is a term most often used today to denote an educational institution. More broadly, it can be the name of any group of colleagues (see, for example electoral college, College of Arms, College of Cardinals). Originally, it meant a group of persons living together under a common set of rules (con- = "together" + leg- = "law" or lego = "I choose"); indeed, some colleges call their members "fellows". The precise usage of the term varies among English-speaking countries.
