Les composé nominaux à premier membre prépositionnel en grec ancien. Le cas de ev°

This thesis deals with ancient Greek nominal compounds with a prepositional first member (FM), and in particular the case of the FM \u1f10\u3bd\ub0. I analyse a great amount of words from a morphological and semantical point of view. The pool of words is based on a formal criterion; the goal of the analysis is to outline different processes of compound formation, as well as their evolution. As compared to other compounds, those with a prepositional FM present two special characteristics: first, they are not formed by two lexemes, since prepositions/adverbs are not real lexemes; secondly, their internal structure is not often recognizable. The guide-questions of this research are: does the special nature of prepositional FM compounds change over different diachronic and diaphasic varieties? Moreover, which are the values of the FM \u1f10\u3bd\ub0 in the different compound categories? Most of the thesis consists in a thorough analysis of compounds attested in three consecutive synchronic phases: first, in archaic epic poetry, then in classical prose of V-IV century (in particular Plato\u2019s and Aristotle\u2019s works); the third part examines all neo-formations appearing in the long period starting from the age of Theophrastus till the age of Nonnus of Panopolis. A brief fourth part presents compounds attested in Arcadian inscriptions, as well as some anthroponyms. In the conclusions, I point out the changes in the value of the FM \u1f10\u3bd\ub0 in the different categories: \u1f10\u3bd\ub0 takes on several functions, that, however, share the signs of a progressive loss of meaning
