The independent possessor (mia 'mine') is relatively rare. In Example 76 it contrasts with the dependent possessive adjective (may/mi 'my').
For the possessive adjective the possessive construction with adposition fi/fu + noun (fu i bonk as in Example 75) alternates with the construction without adposition (i bonk). The pronominal form (fu i/ fu yu/ fu mi/ fi wi/ fi unu/ fu dem) is possible, though rare (speakers seem to avoid it, and use the nominal possessor instead).
But mi/yu/i/wi/unu/dem cannot be used as independent possessive pronouns.
