The Hungarian terminology of wellness. The aim of this study is showing examples for interpreting the terms of Hungarian terminology of the wellness domain as it evolved during one decade. The domain of wellness provides an excellent model for the research of terminological problems, because it has developed from more traditional disciplines and professions (medicine, recreation, physiotherapy, etc.), and the necessary terminological harmonization has not been realized. Detailed examples will be shown for the national differences, the consequences of missing interpretation, the possibilities of ordering, and the necessity of harmonization. The results can be used in other fields of linguistics, for example in the study of theoretical and practical questions of translation.
