ludic [ˈludɪk] a.
1.) Of or relating to play or playfulness (American Heritage Dictionary of the English Language).
Etymology: French ludique, from Latin ludus, play.
"Who am I? Who are you?The question of identity, the Sphinx's question, is at once the tragic and the ludic question par excellence, that of tragedies and that of societies' games; this does not prevent the two levels from occasionally coinciding: in the Maxims (derived from parlor games), in the Truth Game, etc." (The Fashion System by Roland Barthes, Matthew Ward and Richard Howard (trans.), 1983).
