One of the important responsibilities of any teacher at any level is that of planning a sequential program of vocabulary development in each and every area of the curriculum. Vocabulary enlargement must be seen as being a part of the major language arts curriculum of every school in all content departments. All teaching which deals with oral and written words involves concept formation and hence additional words and phrases with their attendant meanings.
