THE EDITOR DESCRIBES THIS BOOK AS "A PRELIMINARY DESCRIPTION OF THE RUDIMENTS OF AYMARA GRAMMAR" RATHER THAN A DEFINITIVE GRAMMAR AND TEXT BOOK. THE MATERIAL FOR THIS BOOK WAS TAKEN FROM THE SPEECH OF EDUCATED URBAN SPEAKERS BILINGUAL IN SPANISH AND THE AUTHOR POINTS OUT THAT MUCH FURTHER FIELD WORK WITH RURAL MONOLINGUAL SPEAKERS SHOULD BE DONE IN ORDER TO DEVELOP A COMPLETE DESCRIPTION OF AYMARA "ACCORDING TO MODERN STRUCTURAL PRINCIPLES OF LINGUISTIC RESEARCH." THE TEXT CONSISTS OF A FOREWORD IN ENGLISH AND SPANISH, 40 LESSONS, AND AN APPENDED AYMARA-ENGLISH GLOSSARY. MOST LESSONS ARE MADE UP OF (1) VOCABULARY (IN AYMARA, SPANISH, AND ENGLISH), (2) GRAMMATICAL ANALYSIS, (3) SUBSTITUTION DRILLS, (4) COMPLETION DRILLS, (5) QUESTION AND ANSWER DRILLS, AND (6) ONE OR MORE DIALOGS. THE DIALOGS UTILIZE IN A NATURAL FRAMEWORK THE VOCABULARY INTRODUCED IN THE LESSON AND THEY PRESENT USEFUL CONVERSATIONAL PHRASES. ALL AYMARA MATERIAL IS WRITTEN IN THE STANDARD ORTHOGRAPHY USED IN LITERACY CAMPAIGNS. INTONATION CONTOURS HAVE NOT BEEN INDICATED BECAUSE THE LESSONS HAVE BEEN RECORDED ON TAPE.
