Abstract
International audience Languages frequently display subordinate clauses introduced with a morpheme similar in form with an adposition (preposition or postposition). The goal of this paper is to give a typological overview of those cases of syncretism adposition/subordinator, on the basis of the formal characteristics of the “subordinate clause”. Those types form a continuum between on one hand cases of a polyfunctional morpheme (functioning as adposition and subordinator) where the subordinate clauses presents the typical characteristics of a clause, and on the other hand cases where only the function of adposition can be analysed, when the “clause” is made comparable to a nominal phrase, through nominalization for instance.
