help me name this suffix

[zaba]

This morpheme attaches to Nouns to mean "this one among others".

eg.

she-ONE.AMONG.MANY 3S-1O-hit
'She hit me' (as I point her out amongst a group of other women)

she 3S-1O-hit
She hit me. (normal usage, I relate an event in the past)

Also:

this-ONE.AMONG.MANY be mine
'this one is mine' (as I select out of a group of other similar things)

this be mine
'this is mine' (normal usage, I am just telling you that the thing belongs to me)

In all my years of work (very few!!!!) I never saw anything like this.
Does anyone have any idea of what it could be? Any x-linguistic example of some suffix it resembles?

Arrrrgh fun but confusing.
Thanks y'all

Some kind of partitive?

[zaba]

My understanding is that the PARTITIVE usually has a meaning like "some", whereas this case is "one among many" -- still I see what you mean and am grateful for the tip. I was up reading about the partitive in several languages including e.g. finnish -- but it seems quite different from what I found. Still, it's the closest thing so far... Any other ideas are appreciated!

What are the other morphemes with which the word can appear?To understand the semantics of the morpheme we need to know that too.

It has a limited distribution, so  tough to say much more -- but it can also be marked with the direct object case marker.

Partitive is generally non-definite, and it tends to have some peculiar behavior as a result. Morphemes with definite semantics usually get called "pseudo-partitives" or (as I prefer) "quantitives".

Maybe better: 'definitive'?

By the way, it sits squarely in a derivational position. Could this be derivational?!
