This paper is an attempt to concentrate on two strategies which constitute text coherence, viz , local and global .These two strategies enable the reader to reach at good understanding for the text .By following the strategies suggested in this paper, the reader is supposed to easily point out the hidden relations in any text. Coherence can be viewed as a covert potential meaning relationship among parts of a text, made overt by the reader or listener through processes of interpretation (Blum-Kulka,1986:17) .The meaning of the word "coherence" is holding together .It is an attribute of texts that are closely constructed so that readers may not be confused about the relationship of its parts .This property of texts is considered by careful writers who transfer the ideas from their minds to those of their readers to give clear and orderly progress from beginning to end .
Coherence is a quality assigned to texts by readers .It is a text –user-centered since it is brought to the text by language users .It resides in the minds of users who assume that as a text is part of a language , it should communicate something .It depends on our ability to detect and interpret meanings not necessarily present in the text .
Correspondingly ,Van Dijk (1977:93) states that these processes are based on the interpretation of each individual sentence relative to the interpretation of the other sentence .
The relatedness of sentence leads to continuity of sense , which is , as Beaugrande and Dressler (1981:84) suggest , the foundation of coherence .They claim that a text makes senses because there is a continuity of senses among the knowledge activated by the expressions of the text .A non-sensical text is one in which text receivers can discover no such continuity usually because there is a serious mismatch between the configuration of concepts and relations expressed and the receivers' prior knowledge of the world.
