ABSTRACT
This chapter discusses the use of formulaic language in a second language (L2) from the perspective of intercultural pragmatics, introducing the socio-cognitive approach as a theoretical frame. It argues that the low rate of formulaic language in L2 does not mean that the idiom principle and economy principle do not affect L2 use. Rather, the low rate is due to two factors. First, besides frequency of exposure, there are several factors such as acceptance, preference, and willingness to use, which are not present in L1 to the extent as in L2. Second, as a compensation for limited use of L2 formulas, L2 learners create new formulaic units, which is the result of individual endeavours or co-construction.
