The story
- French · calque ofsignifiant vide
- English todayempty signifier
First attested in the 1970s, apparently originally a calque of French signifiant vide as used by Jacques Derrida among others (though not by Lacan as sometimes supposed; compare the Lacanian term master signifier). Subsequently popularised in the work of Ernesto Laclau in the 1990s.
