Paradigm

3.3. Interrogative pronouns

In Gothic, like in other German languages, inter pron-s are derived from the stem *xwa-, *xwō-, have masc (ƕas (who)), neut (ƕa (what)) and fem (ƕo (who)) gender and are used only in sing:

singular number
masculine neuter feminine
nominative ƕas ƕa ƕo
genitive ƕis ƕis ƕizos
dative ƕamma ƕamma ƕizai
accusative ƕana ƕa ƕo
instrumental - ƕe -

The form *ƕizos (fem, Gen) is not attested in the surviving Goth sources.
The inter pron ƕarjis (who; which) is also declined like strong adjectives.
