The language of Finnegans Wake is anti-patriarchal. Especially the female narrative in this text challenges patriarchal authority and mastery through her "natural" language. This essay examines the peculiar use of language in Anna Livia Plurabelle`s monologue in Book 4 of Finnegans Wake, so-called `ricorso` which is the last section of the work as well as the last stage of human history in Vico`s theory that provides the fundamental structure of the Wake. The final speech of the work is spoken by Anna Livia Plurabelle who embodies the archetypal female while her husband HCE embodies the masculine. As a river Anna Livia speaks fluid flowing around the dormant husband or the mountain lying near the river. She is old now and her voice is that of all-enduring and self-yielding woman. She recognizes her time has gone and she is ready to accept everything that life has given to her. Her final epilogue is sad but it also hints regeneration. As the sound of river Liffey her speech is lyrical and poetic and it is also soft and rhythmical like that of maternal voice. The flowing slipperiness of her words tends to elude patriarchal control and fixity. Two peculiar characteristics of her language as those of the female narrative are: one is the materiality of language which gives an emphasis on the sound of words rather than their meaning; the other is the strong lyricism. The verbal flexibility implied from these linguistic qualities of female words threatens the laws of language and thus the phallocentric authority. The female Eros, the chaotic and natural maternal feeling couterparts the male Logos, the aggressive and mastering masculine impulse. The spirit of liberation in her "material" and lyrical words becomes a life-force for the living. Here liberation means giving energy to the living, in other words, the liberation of the potential energy of the living. The language of the Finnegans Wake in general transgresses linguistic rules and goes beyond rationality. The chaotic mind of this text undermines the logocentricism. But it is a productive and energizing force for the living and it is suggested obviously by the female language.
