Once again languages for special purposes (LSP)?

This article focuses on the development of LSP research in Germany in order to determine desiderata and to establish priorities for further research projects. Since the 1960s lexicon and grammar of LSP have been described. As a result we now have extensive and mostly even statistically proved results in the fields of morphology, word formation and syntax. In the 1980s research was oriented to a pragmalinguistic description of texts, which made it possible to characterize texts in situational context. Since the 1990s cognitive linguistics has been given more priority, but the results achieved so far are not yet satisfactory. This leads to the question, which topics our attention should be devoted to. There are three groups of problems: Key problems of the theoretical description and systematization of LSP, LSP on conditions of digitalization and globalization, LSP in different contexts (scientific, technical, economic, cultural, administrative etc.)
