Joyce invented a unique polyglot-language or "idioglossia" solely for the purpose of this work. This language is composed of composite words from some sixty to seventy world languages, combined to form puns, or portmanteau words and phrases intended to convey several layers of meaning at once. Senn has labelled "Finnegans Wake"'s language as "polysemetic", and Tindall as an "Arabesque". Norris describes it as a language which "like poetry, uses words and images which can mean several, often contradictory, things at once" An early review of the book argued that Joyce was attempting "to employ language as a new medium, breaking down all grammatical usages, all time space values, all ordinary conceptions of context [... the theme is the language and the language the theme, and a language where every association of sound and free association is exploited." Seconding this analysis of the book's emphasis on form over content, Paul Rosenfeld reviewed "Finnegans Wake" in 1939 with the suggestion that "the writing is not so much about something as it is that something itself [..] in "Finnegans Wake" the style, the essential qualities and movement of the words, their rhythmic and melodic sequences, and the emotional color of the page are the main representatives of the author's thought and feeling. The accepted significations of the words are secondary."
