2.2.1.2. Special anaphoric properties for subject and object
In transitive constructions with plain and agreement verbs, reflexive pronouns, self, can be co-referential with subjects.
ix1b selfb mirror lookb
‘I looked at myself in the mirror.’
In reciprocal constructions with plain verbs, reciprocity is expressed by lexically expressed pointing signs or by hand movement. Pronominal pointing involves a movement from the spatial location of the subject to the location of the object. The sign is then duplicated sequentially in reverse direction.
ix1 → ix2 know, ix2 → ix1 know
‘I know you and you know me’.
