This article is intended to give an overview of all the decisions made regarding the design and compilation of a multilingual terminological dictionary for language teaching and learning. Firstly, the need for a reference work of this nature is justified and then information is provided on the profile of the target readers and the sources used. The following sections are concerned with its general organization and contents with particular attention to the way the information is presented. A final section deals with new developments and future plans, such as the production of a user-friendly online version which will allow for the incorporation of users' feedback and will also include new multilingual glossaries of the entries in other languages apart from those already implemented. The lists of language-related online resources will also be updated and enriched regularly to further enhance the usefulness of the dictionary.
