The First and Second Person Pronouns

s = singular; d = dual; p = plural

The datives can also mean "from", "on", "in", or "with".

Possessive Pronominal Adjectives

The possessive adjectives decline exclusively as strong adjectives (there are no weak forms of possessives). These forms are built from the genitive forms of the respective pronouns, with the addition of adjectival endings, e.g. ek 'I', with G sg. meina, gives adjectival *meina-s > meins 'my' (N. sg. masc.). The forms of meins 'my, mine' serve to illustrate the paradigm.

The second person builds a possessive adjective þeins, and the reflexive pronoun has possessive *seins (as it points back to the subject of the clause, only oblique forms occur). The dual and plural forms of the personal pronouns also build possessives:

The reflexive possessive adjective *seins serves as a reflexive for any number, just like the pronoun itself. The dual possessive *unqar 'of us two' does not occur. Note that final -s (-z) drops after a short vowel followed by consonantal -r (cf. Section 6.2.2), hence the nominative forms of the dual and plural possessives lack final -s. The neuter nominative and accusative singular of the dual and plural possessives do not show the ending -ata. In all other forms, *ugkara- 'of us two', igqara- 'of you two', unsara- 'of us (all), our, ours' and izwara- 'of you (all), your, yours' follow the paradigm of meins.

The third person pronouns have no corresponding possessive adjectives, using simply the genitive forms of the personal pronoun (singular is, is, izos; plural ize, *ize, izo) or of the demonstrative pronoun (singular þis, þis, þizos; plural þize, þize, þizo).

These adjectives are used more often than the 1st and 2nd person pronoun of the genitive case. These adjectives agree in case, gender, and number; and always receive strong adjectival declension. The following grid lists the nominative forms of these adjectives:

The nominative masculine -s is lost after "r" following a short vowel.
