"The girl is giving a fish to it."

Translation: Riña klios jāhot irughas.

[Gelgisith]

Why is "jāhot" (3rd person aqua./terr. dative possessive pronoun), in stead of "ūjōt" (3rd person aqua./terr. dative pronoun) used here?

(Edited to replace the erroneous "adjective" with "pronoun". The possessive pronouns are declined like adjectives, hence my mistake.)
