Tatediem: Pronominal Possession, Indirect Objects

Tatediem marks indirect objects - these can only be humans, btw - by a specific set of prefixes (that in part are 'subsumed' in the object slot, generally prefixing themselves to the object prefix with some level of assimilation).

	1		2		3
	masc	fem	masc	fem	masc	fem
sg	-heŋ-	-heŋ-	-win-	-wir-	-ŋme-	-har-
dual	-hami-	-himi-	-sin-	-tir-	-ŋra-	-ŋar-
pl	-hew-	-hig-	-cin-	-cin-	-ŋim-	-lar-

Which, by the way, reminds me that I have not yet given the personal pronouns! Here, feminines to the right, masculines to the left:

	1		2
	subj	obj	subj	obj
sg	-ke-, -ke-	-her-, -hec-	-gi-, -gi-	-wir-, -ŋwiŋ-
dl	-am-, -im-	-kiim-, -kaam-	-di-, -tin-	-sir-, -sin-
pl	-eg-, -ic-	-xec-, -ki-	-gi-, -gi-	-cir-, -cir-

As for expressing possession, the object prefixes can be affixed between the gender prefix and the root of a noun. However, many dialects have opted for marking an empty verb-like particle in the vicinity with the gender of the possessed noun (as subject), and the dative prefix (or the object prefix for dative-less nouns) as the object. The verb is -gìan-, a verb that in some dialects also can serve as copula. It lacks all other markings except subject and object. 

Conversely, some dialects use -páhí-, 'possess', and have a somewhat different structure - the possessor as possessor, and the possessee as subject. If the possessor has a dative marker, the possessee is marked with that prefix in the subject slot, whereas if the possessor is of some other gender, the possessor has a subject-like marking and the possessum has an object marking.

Thus

ye-ŋəbs = the dog
ye-her-ŋəbs = my dog
ye-kiim-ŋəbs = the dog belonging to the two of us
ye-ŋim-ŋəbs - their dog
(assimilation often hits: yeki:ŋebs/yeki:mbs, yeŋiŋəbs/yeŋ:ibs) 

But also:

 (ye-)ŋəbs ye-heŋ-(g)ìan = a/the dog that belongs to me (assimilated as yeŋəbs yeŋ:ì:n)
(ye-)ŋebs heŋ-ye-páhí = a/the dog that I own (assimilates to yeŋəbs heypáí)
(ye-)ŋebs ku-l-páhí = the dog that belongs to neut1 noun 

Sometimes, the prefix relating to the possessum is omitted from -(g)ìan or páhí, if it is definite:

yeŋəbs heŋian
yeŋəbs kepáhí
