“In order to understand a text a reader should be able to distinguish a text from a piece of language which is not text. Sentences in a text are not put together haphazardly, but they possess unification and unity which is called texture” (Halliday & Hasan, 1976:5). The cited authors believe that “ if a passage of English containing more than one sentence is perceived as a text, there will be certain linguistic features present in that passage which can be identified as contributing to its total unity and giving it texture.”(p. 2).
