Pronominal possessors usually simply precede the possessed. A suppletive form su is used for the 3rd person singular pronoun (perhaps because the 3SG nonpossessive pronoun e is homophonous with the definite article e); other pronominal possessors are identical to the subject forms of pronouns.
The adpositional construction with di is far less frequently used, and possibly associated with a slightly emphatic reading; this might be worthy of investigation.
Finally, plural pronouns are prosodic words (Kouwenberg 2007), which means that they may behave as full nouns, and appear in the dislocated possessive construction, with a prenominal possessor followed by su. This construction is discussed in more detail under Feature 38 "Marking of possessor noun phrases".
