Routine formulae are highly frequent, situationally bound chunks that are beneficial to L2 learners' pragmatic performance. These formulae are usually more easily acquired in the target language setting but they are to some extent also learnable in foreign language classrooms. This study investigates the effect of different lengths of residence abroad on the recognition of situational routine formulae. A total of 262 ESL and EFL learners completed a test battery which included assessment of receptive knowledge of routines. Learners with even short-term residence of two months had increased knowledge of routines, and further residence led to further improvement in knowledge in this area. Even EFL learners without residence knew some routine formulae but knowledge of routines was independent of general proficiency. Learners in the L2 setting get routines "for free" through exposure to contextualized L2 discourse, but which specific routines are acquired depends on the interactional settings in which learners communicate.
