Institute (from Lat. instituere, to establish or set up), something established, an institution, particularly any society established for an artistic, educational, scientific or social purpose. The word seems to have been first applied in English to such institutions for the advancement of science or art as were modelled on the great French society, the Institut National (see Academies). It is thus the name of such societies as the Royal Institute of British Architects, the Imperial Institute and the like. It is extended to similar organizations, particularly to educational, on a smaller or local scale, such as Mechanics’ or Workmen’s Institutes, and is sometimes applied to charitable foundations. In the United States the word is, in a particular sense, applied to periodic classes giving instruction in the principles of education to the teachers of elementary and district schools. The term “institute” is often used to translate the Lat. institutio, in the sense of a treatise on the elements of any subject, and particularly of law or jurisprudence; thus the compilation of the principles of Roman law, made by order of the emperor Justinian, is known as Justinian’s Institutes, and hence Coke’s treatise on English law, of which the first part is better known as Coke upon Littleton, is called The Institute. The same title is borne by Calvin’s work on the elements of the Christian doctrine. In Scots law “institute” is the person named, in a settlement or testament to whom an estate is first limited; those who follow, failing him, are termed “substitutes.”
