cloistered

The word "cloistered" traces its lineage to the Latin verb claudere, meaning "to close or shut." Its nominal derivative, claustrum, signified an enclosed space, such as a lock, barrier, or confined area. This term passed into Old French as cloistre, specifically denoting the secluded courtyard of a monastery, and entered English with this architectural and religious sense. The suffix "-ed" was then appended, transforming the noun into an adjective that describes either the physical state of being provided with such an enclosure or, more abstractly, the sheltered and secluded way of life it represents.
