Postulant
（重定向自Postulancy）
A postulant (from Latin:postulare, to ask) was originally one who makes a request or demand; hence, a candidate. The use of the term is now generally restricted to those asking for admission into a monastery or a religious institute, both before actual admission and for the period of time preceding their admission into the novitiate. Currently, however, common usage terms the person who has not yet been accepted by the institution as an "inquirer" or "observer".
