Catholicos, plural Catholicoi, is a title used for the head of certain churches in some Eastern Christian traditions. The title implies autocephaly and in some cases is borne by the designated head of an autonomous church, in which case the holder might have other titles such as Patriarch. In other cases a catholicos heads a Particular Church and is subject to a patriarch or other church head. The word is a transliteration of the ancient Greek καθολικός, pl. καθολικοί, derived from καθ' ὅλου (kath'olou, "generally") from κατά (kata, "down") and ὅλος (holos, "whole"), meaning "concerning the whole, universal, general"; it originally designated a financial or civil office in the Roman Empire.

The Church of the East, some Oriental Orthodox, Eastern Orthodox churches, and some Eastern Catholic Churches historically use this title. In the Church of the East, the title was given to the church's head, the Patriarch of the Church of the East; the title Catholicos is also used for the head of the Armenian Apostolic Church and the Georgian Orthodox Church. In the Syriac Orthodox Church the Catholicos of the East was given to the Maphrian, historically an office below the Syriac Orthodox Patriarch of Antioch.

A great house is a large and stately residence; the term encompasses different styles of dwelling in different countries. The name refers to the makeup of the household rather than to any particular architectural style. It particularly refers to large households of times past in Anglophone countries (especially those of the turn of the 20th century, i.e., the late Victorian or Edwardian era in the United Kingdom and the Gilded Age in the United States), such as the English country house, the "stately homes of England" and the homes of various "millionaires' row" (or "millionaires' mile") in some U.S. cities such as Newport, Rhode Island, with luxurious appointments and great retinues of indoor and outdoor staff. By some reports, the summer homes of the wealthy at Newport averaged four servants per family member. There was often an elaborate hierarchy among staff, domestic workers in particular. In Ireland, the term big house is usual for the houses of the Anglo-Irish ascendancy.

It was considered declassé to refer to one's own townhouses, estates or villas (or those of friends) as mansions and modern etiquette books still advise that the terms house, big house or great house be used instead.
