comparative adjective

an noun modifier taking a comparative form of an adjective and standing in apposition; the c. a. is generally in Latin, e.gg., Superior, Junior, Senior, but may be the English version, e.gg., the younger, the elder, in which case it may be a descriptive name serving as a surname; the c. a. is introduced in PS-RULE [PS12] in two parts: the adjective root and the comparative marker; the c. a. is a postpositive title phrase standing between any rank (“Mother”) and post-nomial initials; hence we have “…Maria Angelica, Mother Superior, S.C.” or “…Jones, Jr., M.D.”
