module

module. 1 Term derived from the Latin modulus, a unit of measure in classical architecture equal to half the diameter of a column at its base. This unit was used in proportioning the classical orders of architecture. 2 The modern module is an interchangeable building unit used in construction; these units are mass-produced and therefore easily replaced and economical.
