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, for example, an electoral college, a College of Arms or the 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 the English-speaking countries.
