The aim of this article is to analyze the uses of c’est le cas de ‹this is the case of› and prendre le cas de ‹take the case of› in their function as markers of the exemplification relation. To this end, the first part is devoted to a lexicographical and cooccurrential exploration of the words cas ‹case› and exemple ‹example›, in order to identify elements that can be used to characterize exemplification uses. An examination of c’est le cas de shows that the expression is not always exemplifying (it can also be generalizing), and if prendre le cas de is a marker of exemplification, it can have as its object the non-observance of the general property at stake in the statement.
