In Diu Indo-Portuguese, pronominal possessors occur before the noun they modify (the possessum).
The first person possessive pronouns are clearly separate words: the 1SG possessive pronoun is mĩ, which is formally equivalent to the oblique form of the 1SG personal pronoun; the 1PL possessive pronoun is nɔs, formally equivalent to the 1PL personal pronoun (which does not have a separate oblique form).
Second and third person pronominal possessors are classified in this study as (preposed) prepositional phrases rather than possessive pronouns, but this is admittedly a matter of interpretation; it is equally possible that the preposition də has fused with the subsequent personal pronouns to the extent that the complexes now form single words - which would then be classified as possessive pronouns. I have opted for the former interpretation in view of the following:
(a) the combination of the preposition də and a personal pronoun as pronominal possessors is entirely expectable given that non-pronominal possessors also take the form of də-PPs;
(b) the preposition də is observed to undergo similar phonetic reduction in combination with other vowel-initial words, such as the demonstratives (e.g. də + ikəl = dikəl) or the numeral/indefinite article ũ (də + ũ = dũ); it is therefore unwarranted to interpret the phonetic integration observed in pronominal possessors as proof of grammaticalization;
(c) although the preposed position of these elements does contrast with the typical order of non-pronominal possessors, there are various examples of (atypical) preposed non-pronominal də-PPs; the constraints against these cases seem to involve heaviness rather than categorial distinctions.
Very rarely, a pronominal possessor may be postposed to the head noun. In such cases, first person possessive pronouns are replaced with a de-PP (the typical non-pronominal possessor manifestation and position).
