The aim of the presented collective monograph “Slovanské spisovné jazyky od teorie k praxi. Formování jazykového vědomí a postojů k jazyku (Slavic standard languages from theory to practice. Formation of language awareness and attitude to language)“ is to reveal the way in which the field of linguistics communicates with the wider public, the process of formation of conscious language awareness, and the implementation of theoretical concepts and interventions into practical use. Analysed are the institutions, their actions and means (influence on language function in the public domain, codification interventions and their consequences, language policy in relation to the language situation, the educational system and particularly teacher training, the government of science and its popularization, and many others), as well as the leading actors of language policy. The main focus of the theory of standard language in Slavistics was placed predominantly on pre-existing academic discourse, which gives rise to the theoretical concepts and interventions. Attention is also paid to the subsequent evaluation of the impact and consequences of the implemented policy (standard language forms, mother-tongue speaking competency, language policy making). The contribution from Stanisław Gajda (Język literacki w po-nowoczesności) on the theory of standard language, focussing on the role of language in the post-modern society in an interdisciplinary context, bridges across all of the presented works. According to Gajda, a good theory demonstrates a high degree of ‘reasonableness'with respect to theoretical reality, generalizability (the better the theory, the wider range of observations can be explained), economy (the fewer concepts and theorems require an introduction the better), external and internal consistency (the basic terms and theorems are in line with well-established scientific findings), and explanatory and predictive power. Histories of individual national standard language gains are varied, however in principle they each consider implementation of a common communication tool as a prototype, an idealized construct. A complete theory possesses a complex hierarchical arrangement, identified by three levels: philosophical, theoretical / methodological, and empirical. However, actual science often encounters incomplete theories, which do not contain elaborated levels and are commonly limited to an empirical level. Following presentation and historical description of aspects describing standard lan270 slovanské spisovné jazyky od teorie k praxi guage, S. Gajda focuses on selected aspects of the present state of language theory. In particular, he focuses on the impact of the transformation in communication media and two aspects of current social changes: the character of a post-modern societal environment and the process of socialization on an individual level. In the analyses and syntheses that follow several of these ideas are elaborated, not only empirically, but importantly also in terms of implementation. Ondřej Bláha (Etnická a jazyková identita obyvatel Moravy po roce 1989;) concerns the ethnic and language identity of the Moravians within the framework of the Czech language community. It investigates the relationship between the ethnic and language identities (in general, seven times more people consider themselves as ethnically Moravian, than those who define their language as Moravian). Processes are identified either based on census statistical data (between the years 1991–2011) or on the attempts to codify (or describe) Moravian language. It evidences a subjective and political background behind emancipation tendencies among Moravians and offers a classification of the somewhat naive manifestations of “the search for Moravian language” – efforts to define and standardize a Moravian language, distinct from Czech language, or efforts to introduce aspects of Moravian dialect
