This paper tries to shed some light on the problem of synonymy in the specialised discource in Arabic, where the scientific notion or concept is reffered to with more than one term or denomination. It’s well-agreed upon that the accuracy of scientific discource requires a corresponding accuracy in terminological use in order to facilitate interaction among experts and specialists. This is not the case of Arabic wherein one scientific notion or concept or phenomenon is very often denominated with more than one term, especially if we take into account the terminology used in the Arab countries of the Gulf and that used in North Africa where we notice a large difference in terms of scientific denomination.The Arabic scientific discource faces the instability of usage of the terms translated from foreign languages ; one scientific term in English or French has different Arabic equivalents, this is what linguists call synonymy in specialised languages. This terminological variety is not, in fact, a feature of linguistic richness but rather an obstacle that hinders all efforts to achieve a unified and accurate scientific discource. From this standpoint this paper will try to tackle the problem of synonymy studying and analysing it from different angles and illustrating it with examples from a variety of domains.
