Did you know?

Cloister first entered the English language as a noun in the 13th century, referring then (as it still does) to a convent or monastery. More than three centuries later, English speakers began using the verb cloister to mean “to seclude in or as if in a cloister.” Today, the noun can also refer to the monastic life or to a covered and usually arched passage along or around a court. You may also encounter the adjective cloistered with the meaning “separated from the rest of the world [as if in a cloister],” as in “She leads a private, cloistered life in the country.” Cloister ultimately comes from the Latin verb claudere, meaning “to close.” Other words that can be traced back to the prolific claudere include close, conclude, exclude, include, preclude, seclude, and recluse.
