This new study is a major contribution to sign language study and to literature generally, looking at the complex grammatical, phonological and morphological systems of sign language linguistic structure and their role in sign language poetry and performance. Chapters deal with repetition and rhyme, symmetry and balance, neologisms, ambiguity, themes, metaphor and allusion, poem and performance, and blending English and sign language poetry. Major poetic performances in both BSL and ASL -- with emphasis on the work of the deaf poet Dorothy Miles -- are analyzed using the tools provided in the book.
