The paper discusses the terminology used in an EU document. It is part of a recently started research project on labour law terminology and terminography. Directive 2002/15/EC, the document selected for analysis, is an example of EU text dealing with two subject fields: labour law and road transport. Apart from that, it presents specialised vocabulary typical of EU documents. Analysing this directive enabled the author to compile a record of terms in the three fields: labour law, road transport law, and EU legislation, and then analyse them according to several classifications: the field of study, the type of concepts represented, and the length of terms (the number of words, a formal criterion). The proportions calculated made it possible to draw some conclusions as to the specialised vocabulary found in EU legal texts from the viewpoint of a translator and a terminologist, who need to be familiar with all the topics discussed in texts they are dealing with in a given job.
