Khulusi studies Shakespeare's language in terms of its grammar and compares this to Arabic grammar. According to Edwin Abbott (Shakespearian Grammar 1870), Shakespeare's language is unique in that he prefers clarity to grammatical correctness, and brevity to both correctness and clarity, leaving sentences unambiguous but seemingly ungrammatical.[27] Khulusi suggests that Shakespeare's grammar should not be analysed by the fixed rules of modern English, as Elizabethan English was far less structured and in a 'transitional phase' of development.
