I'll continue to edit this.
Personal Pronouns
These consist of personal actants (including number) + a pronominal root / / + case endings. They're used in focus and topic positions.
Possessive Pronouns
These are actually forms of 2-consonantal root verbs meaning "belong to" (possibly /ml/) with
A2 actants (including number). Note that possessive pronouns aren't used with words having inherent possessors.
Proximal and Distal Determiners
These have both short and long forms. The short forms consist of the 3rd person actants (without number) + the case endings. One of these short combinations doesn't exist (specifically, *yii) and is replaced by the corresponding long form. The long forms consist of the 3rd person actants + /eqq/ + the case endings.
Definite Determiner
This also has short and long forms, formed as above with /w/ used as the actant. The short forms *wuu is replaced by the corresponding long form.
