The property of extraction is related to the movement of a constituent to the left edge or to the right edge of the sentence. This happens in wh-questions (SYNTAX 1.2.3) or topics (PRAGMATICS 4.2). In LIS, extraction out of a coordinate structure is possible if the same constituent is extracted from both coordinated conjuncts. In the example below, what is interpreted as the object of the verb in both conjuncts.
neg wh
mother like father like.not qartichoke
‘What does mother like and father not like?’
The following is another case of extraction of a constituent (orange ix) out of coordinated clauses through topicalisation.
top
orange ix mother like father impossible_no_way
‘As for oranges, mother likes them and father dislikes them.’
In the examples above, the extracted constituent is the object of the verb in each coordinated conjunct.
