Abstract This article reports an interview with Robert D. Van Valin, Jr., which was held on March 2, 2023, with follow-up e-mail exchanges. Robert Van Valin is the primary developer of Role and Reference Grammar (RRG), a syntactic theory whose principles and commitments intersect with those of Cognitive Linguistics (CL). The article discusses RRG vis-à-vis CL and other approaches to the study of language. It aims to raise awareness about the shared principles of RRG and CL, to enhance cross-fertilization between the two approaches and ultimately inspire new research directions in linguistic theory. The paper is organized into three main parts: (i) background information on the birth and development of RRG, (ii) general principles and commitments of RRG and CL, and (iii) specific issues in the study of language.
