Démonstratifs : emplois à la mode et mode(s) d'emploi

This paper is devoted to demonstrative markers. Not to standard demonstratives such as ostensive or anaphoric demonstrative noun phrases, but to unwonted uses. Our aim is to show how to deal with such unusual and very strange referring demonstrative expressions. Two points are specially taken into consideration : (i) in the first section, the necessity to define and delimit this new uses ; (ii) in the second section, the difficulties which arise during their analysis.
