This opening article introduces the reader to current topics in research on language and thought in monolingual speakers and second language (L2) learners, with particular attention to the domain of motion. The article also delineates the rationale that underlies the special issue at hand, and provides a contextualisation of the individual contributions. It is argued that the centrality of motion in everyday human life, in combination with the vast cross-linguistic variation in motion construal, makes motion events a suitable topic for SLA research, both in terms of ecological validity and learnability challenge. The pedagogical aspects of this line of research are discussed in terms of, first, whether it is desirable to include the acquisition of language-specific thought patterns in curricular goals, and second, whether the knowledge about language specificity in thought can be used in teaching as a means to facilitate learning.
