THIS WORKBOOK WAS WRITTEN TO ENABLE PEACE CORPS VOLUNTEERS LIVING IN THE PHILIPPINES TO ANALYZE AND LEARN THE LANGUAGE SPOKEN IN THEIR REGION. IT WAS ASSUMED THAT THE VOLUNTEER WOULD HAVE SOME TRAINING IN TAGALOG BUT NOT NECESSARILY A KNOWLEDGE OF LINGUISTIC TERMS OR METHODS. THE AUTHOR ALSO ASSUMES THAT THE VOLUNTEER WILL WORK WITH A NATIVE INFORMANT AND THAT THE LANGUAGE BEING STUDIED IS SIMILAR IN PHONOLOGY AND GRAMMAR TO TAGALOG. SECTION I OF THE WORKBOOK GIVES A BRIEF OUTLINE OF BASIC PRINCIPLES OF PHONOLOGY AND MORPHOLOGY. NO SYSTEM OF PHONETIC TRANSCRIPTION IS PRESENTED. THE STUDENT IS TAUGHT TO FORMULATE AND TEST HIS OWN GRAMMATICAL RULES FOR THE LANGUAGE. SECTION II SHOWS HOW COMMON CONSTRUCTIONS ARE FORMED IN TAGALOG AND ENGLISH. THE STUDENT THEN LOOKS FOR CORRESPONDENCES OR VARIANT PATTERNS IN HIS TARGET LANGUAGE. THE FINAL SECTION LISTS COMMON, VERY USEFUL EXPRESSIONS IN ENGLISH WHICH THE VOLUNTEER MAY WISH TO TRANSLATE AT AN EARLY STAGE IN HIS ANALYSIS OF THE LANGUAGE. (JD)
