Conditional concessive clauses, typically introduced by ‘even if’ in English, are a construction in which the truth of the proposition expressed by the antecedent clause does not affect the truth of the proposition expressed by the consequent clause. An example of a concessive conditional clause in LIS is provided below.
cond
ring 3donate1 ix1 same accept not
‘Even if s/he gave me a ring, I wouldn’t accept it.’
Concessive conditionals have the same structure of concessive clauses (SYNTAX 3.5.7).
