Trois exemples d'ambiguïté syntaxique liés au fonctionnement régi et non régi de <i>ça</i>

The aim of this paper is to describe some particular uses of the French pronoun <i>ça</i>, which is not always the informal equivalent of <i>cela</i>, since they cannot both commute in every context. Indeed, in three cases such as: <i>il est plus gros que ça</i> (<i>'it is bigger than this'</i>); <i>qui ça?</i> (<i>'who did you say?'</i>); <i>faire ci et ça</i> (</i>'to do this and that'</i>), it cannot be decided if <i>ça</i> is still a pronoun or if it adds emphasis to a sentence.
