Heurs et malheurs de la terminologie arabe d’origine étrangère

After a brief presentation of the status of Arabic terminology in the official organisms (the academies) and the current state of the terminology of linguistics and space science, this article outlines the results of a comparative study (French-English-Arabic) conducted on the terminology of space science and linguistics. The objective is to study the fate of neologisms in scientific discourse and dictionaries. A comparison between the usage of these neologisms and their attestations in monolingual and bilingual dictionaries and in databases makes it possible to determine the means by which these neologisms are consecrated in the language and consequently how they are lexicalized. The focus is on the role played by common usage and the different dictionaries in this process.
