The same manual markers used in the antecedent of factual and counterfactual conditional clauses may be optionally employed to mark the antecedent of concessive conditional clauses (SYNTAX 3.5.1.2.2). In addition to them, the concessive interpretation is obtained through the obligatory use of the manual markers illustrated below: same(a) and same_before (b). Other synonyms of these signs may also be employed.
a. same
b. same_before
The manual markers same and same_before are produced in the consequent clause, either before or after the subject.
cond
libia ix(loc) trip 3donate1 ix1 same go not
‘Even if s/he donated me a trip to Libia, I wouldn’t go.’
In the presence of the optional manual marker occurring in the antecedent clause, the obligatory non-manuals marking the antecedent clause are also produced. When the manual marker in the antecedent clause is absent, the obligatory non-manual markers alone are able to mark the sentence as a conditional clause.
