Abstract:In this essay I try to argue a broader and deeper notion of fairy tale, beginning from an overview of some of the key terminologies and classifications devised and employed by folk-narrative research, passing through an etymological and semantic scrutiny of the word 'fairy', and developing, eventually, a structural analysis purposely framed within the historical-cultural context of the Irish tradition. What I attempt to let emerge -challenging to some extent the established concepts and theories -is a more comprehensive narrative category, characterised by a specific epistemological and ontological value, through which a sort of intermediate, neutral space is modelled, where boundaries are crossed and elements more or less heterogeneous are connected. Thus, the fairy tale can express a multi-dimensional worldview and the potential for a more complex idea of reality.
