Caenobium

The Radiolaria are marine rhizopods, whose unicellular body always consists of two parts,— […] The individuals are usually single: in only a small minority are the unicellular organisms united in colonies or caenobia.

Sometimes it [the church] is called Martyrium, when raised in honour of any Martyr; somes capella, (chapel,) … sometimes caenobium, at others sacrificium; sometimes sacellum; sometimes the House of Prayer; sometimes monastery; sometimes oratory.

The Encomiast refers to St. Bertin's and St. Omer's as monasteria (II, 21, I and II) and caenobia (ibid., 15). […] The words monasterium and caenobium are, however, both freely used in medieval Latin in the sense 'collegiate church'.

An anagārika does not formally commit himself (or herself) to the strictly cenobitical monastic restraints of a caenobium or monastery, such as finishing one's begging round for food before midday, and not handling money.
