This overview to "The Modern Language Journal"'s Focus Issue on Languages for Specific Purposes (LSP) takes a fresh look at issues examined in a 1991 article by Grosse and Voght. Reflecting on change drivers and growth in LSP, the authors comment on current challenges to the field and future research needs. Their remarks are based on new insights from the Focus Issue authors, a review of literature, and their own observations. From 1991 to 2011, the field of LSP in the United States evolved from a minor role in the foreign language (FL) curriculum, primarily in business languages, to one with a wider base in FLs and interdisciplinary studies. Amid calls for structural changes in language departments from the Modern Language Association (MLA) and the push to internationalize professional school curricula for accreditation, LSP practitioners face exciting new opportunities for service and research. The continuing evolution of LSP doubtless will bring further integration of language, culture, and content to the academic and professional worlds. (Contains 1 note.)
