Mapping the genetic genealogy between Lewis Carroll and James Joyce, this essay analyzes how Carroll scrutinizes the nature of language and performs language experiment in Alice series, how these texts exemplify Saussrean theory and linguistics, and how Joyce’s Finnegans Wake develops Carroll’s precursory experimentation. Carroll’s word play in ‘Jabberwocky’ anticipates Joyce’s full-blown language experiment in Finnegans Wake. Carroll’s and Joyce’s language experiment, in which they coin new words, combine words in an unconventional way, spell words backwards, and visualize the meanings of words typographically, represents a whole new level of signification and dismantles the rigid social order of Victorian society and British colonialism, respectively. Both Carroll and Joyce are rebels using language as a weapon in order to construct their own “wordsland.”
