Pal.gr.108

The remaining [possessives] are derived from the nominatives of the duals of the plurals: from the nominative of the duals of the first person, which is nōï nominative or nōï oblique; [namely] the nōï oblique. These are used whenever only two share the possession. And they are not from the nominative of the second person, which is sphōï person or sphōï oblique; [namely] the sphōï oblique. From the third person, no possessive pronoun is derived; for the third person does not have a nominative among the duals.

From the nominative of the plurals plurals of the first person: ho hēmeteros, hē hēmetera, to hēmeteron. These are used whenever many share the possession. From the nominative of the second [person]: ho hymeteros, hē hymetera, to hymeteron. From the third person: ho spheteros, hē sphetera, to spheteron.

There are also, among the poets, other possessives following the sequence of those [derived] from the nominative plurals: ho hamos, hē hamē, to hamon, instead of ho hēmeteros, hē hēmetera, to hēmeteron. ho hymos, hē hymē, to hymon, instead of ho hymeteros, hē hymetera, to hymeteron; as in Homer: "for he knows our city is protected [by] yours." ho sphos, hē sphē, to sphon, instead of ho spheteros, hē sphetera, to spheteron. ho sphos: the [form] sphos [is written] with the η. ε is the one in Hesiod and "might be present in their [minds]."

These, then, are possessives. There are also demonstratives and pronunciations besides these. These are as follows: houtos, hautē, touto; ekeinos, ekeinē, ekeino; ekeinou. As follows: houtos, toutou, toutō, touton, ō houtos. The duals: toutō, toutoin, ō toutō. The plurals plurals: houtoi, toutōn, toutous, toutois, ō houtoi.
