Translating texts on social policy into several languages, comparing the social policies and social reality of different member countries, and transferring social policies across national borders are becoming more and more important for European integration. At the roots of these issues, the question of translation is found; since to compare and transfer, one must first translate. So the objectives of the paper are to present some reflections on the translation process, and to outline and explain the main difficulties faced, in particular in the field of social policy.
