Did you know?

Cloister first entered the English language as a noun in the 13th century; it referred 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 cloistered with the meaning "surrounded with a covered passage," as in "cloistered gardens." Cloister ultimately derives 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.
