As described in the previous post, Ćwarmin has a special accusative for reflexively possessed objects. This combines with some normally intransitive verbs - to be, to stand guard, to become, to go - to create predicative possession.
The simplest construction is along these lines:
SUBJECT.nominative is[inflected for tense, aspect, person] OBJECT.refl.poss.acc
~subject has object
The owner can sometimes also be in the dative, in which case the verb omits agreement.
More complicated things appear with various voices. The language has two passives - one that promotes the direct object to subject, and one that promotes the indirect object. Sometimes, the indirect object passive (henceforth passive II) is used for predicative possession as well:
SUBJECT.nom is.passII.[tense,aspect,person] OBJ.refl.poss.acc
The third person passive II is used when having in general is discussed, or when no object is supplied:
be.passiveII.participle = those who have
be.passiveII money.refl.poss.acc is nice = to have money is nice
Further, usually, to stand guard, takes a locative complement. The ablative can be used to mark guarding against something. It being used to denote possession often relates to certain objects that often are guarded in the Ćwarmin culture - homes, flocks, individual animals, slaves, daughters, but also honor, titles and duties and by extension any noun of which one is especially proud. To stand mainly is used when the object is land, resources, ships, a shed or otherwise work-related building, rights and equals or above in status (brothers, friends, owners, masters, etc). To go is used in a possessive sense whenever the object actively obtained, to become when it is bestowed upon the subject.
