Untrained writers usually believe that once a person has learnt how to write in a particular language he becomes a good writer in that language in different disciplines. This is an incorrect assumption. In fact, each discipline requires a different language and style for good writing.Each discipline has its own terms which have specific meanings when used in connection with that particular discipline whereas such terms may have quite different connotations when used in common language. For example, the phrase, “class struggle” has specific meanings in Political Science which refer to the theory of Karl Marx but in common language it may not mean the same. Similarly, the terms, “status”, “group” and “society” refer to specific concepts of Sociology but are used in different meanings in common language.Using hedge-words such as, “may”, “might”, “seems” or “probably” while commenting upon a literary work is considered to be a sign of indecisiveness of the writer. He is expected to use a confident language while stating his conclusions. In the sciences and social sciences, a sensible writer knows that the conclusions he has drawn are not final and that theories are subject to change as a result of research and experiments carried out by others. Consequently, he uses hedge-words to leave some room for change in his conclusions. In the humanities, colorful language adds to the degree of eminence of a writer but is considered to be inappropriate in sciences where the purpose is to highlight the points being raised and not the language.A good writer must be aware of the significant variations in writing for different disciplines.
