A refectory (also frater, frater house, fratery) is a dining room, especially in monasteries, boarding schools, and academic institutions. One of the places the term is most often used today is in graduate seminaries. It is derived from the Latin reficere: to remake or restore, via Late Latin refectorium, which means a place one goes to be restored.
