The numeral one is used as an indefinite [Pragmatics - 1.3.] article in the following NP, [one research].
ix(:)1 [one research] share want
'I want to share a (piece of) research'
A pointing sign, ix, can be used to introduce a referent [Pragmatic - 1.]. This is called locus assigning (ix(loc)a). After this, a pointing pronoun (ix3a) is directed to the same location. The pointing sign now functions as a pronoun [Lexicon - 3.7.] as given below.
[poss(d)1 frienda ix(loc)a] ear ache. today ix3a home stay want
'My friend has an earache. She wants to stay home today.'
(r.f. from Nuhbaloฤlu and รzsoy 2014: 9)
A noun phrase can contain both a possessive pronoun and a locus assigner as the following example shows.
poss(d)3 father ix(loc)a
'His father (who I am assigning to this location loc-a in space)'
The indefinite article one can also be used with a locus assigner.
one man ix(loc)a
'A man (who I am assigning to this location loc-a in space)'
A definite article is used to refer to a referent that is already introduced into the discourse, namely both the signer and the addressee know about this referent. A pointing sign that accompanies a noun can be used as a definite article in TฤฐD.
[ix(def) man] look_for
'The man is looking for (the frog).'
