Language is the basic means of communication in the classroom. It is therefore vital that teachers should know something about its acquisition, development, possible defects and the ways in which they may understand and develop its communicative powers.

Peter Herriot describes the relationship with thinking, with personal and social development and its manifestations in the classroom. All this is described from the point of view of the psychologist and incorporates many of the findings of contemporaneous psychological research. But the author carefully avoids the jargon of psychology nor does he assume any prior knowledge of linguistics or psychology. Thus Language and Teaching should be especially useful to the student of education or those already engaged in teaching. It is a primer of communication.
