Where a lexical possessor precedes a possessed noun, a possessive of the form POSSESSOR + PN + POSSESSED must be used. The pronoun which separates possessor and possessed is the third person possessive pronoun su. Muller (1989: 538f) and Maurer (1988: 38) show that it acts as a generic possessive pronoun in this construction. See Feature 38 "Marking of possessor noun phrases" for further discussion.
