3.4.6.2. The spreading domain of each non-manual marker
In general, the various non-manual markers are aligned with each other. If there is a manual relative pronoun (pi or person-cl), the non-manual markers spread on the relative pronoun and can optionally extend over the head noun of the relative, as shown in the following example.
rel
ix1 prefer dog pi man pet
'I prefer the dog which the man pets. (Hauser, 2019)
When there is no manual relative pronoun, only the head of the relative clause is marked through the set of non-manual markers, see in the example below.
rel
ix1 prefer vet cure dog
‘I prefer the vet who cures the dog.’ (Hauser, 2019)
