Does collocation congruency between L2 and L3 play a role in processing L3 collocations?

Previous research has shown that L1-L2 congruency is a facilitative factor in collocation processing. The present study explores the effect of congruency between learners’ L2 and L3. Thirty three proficient Norwegian learners with Lithuanian as their L1 and English as L2 took a phase acceptability task consisting of three groups of Norwegian collocations: congruent with L2, congruent with both L1 and L2, and incongruent with both. The results revealed that collocation L2-L3 congruency facilitates collocation processing.
