PART ONE, PHONOLOGY, IS CONCERNED WITH A DESCRIPTION AND EXEMPLIFICATION OF THE PHONEMES OF SANGO, A DISCUSSION OF THE VARIATIONS BETWEEN WORDS WHICH RESULT FROM DIFFERENT KINDS OF PHONOLOGICAL CHANGES, AND A DESCRIPTION OF THE INTONATIONAL FEATURES OF THE LANGUAGE. PART TWO, WORD CLASSES, DESCRIBES THE SIX CLASSES OF WORDS IN THE LANGUAGE (PRESENTED IN ALPHABETICAL ORDER)--ADJUNCTIVES, CONNECTIVES, NOUNS, PRONOUNS, SENTENCE PARTICLES, AND VERBS. PART THREE, CONSTRUCTION CLASSES, DESCRIBES VARIOUS TYPES OF UNITS WHICH CONSIST OF MORE THAN ONE WORD. FIRST THERE ARE PHRASES, SUBSTANTIVE AND VERB. THEN THERE ARE PRECLAUSAL AND SUBJECTIVAL CONSTRUCTIONS WHICH ARE NOT COORDINATED IN THE STRUCTURE WITH THE PRECEDING BUT ARE MORE PROPERLY FUNCTION CLASSES. FINALLY THERE ARE NONVERBAL AND VERBAL SENTENCES, FOLLOWED BY A CHAPTER ON QUESTIONS AND PROCESSES. PART FOUR, TEXTS, PRESENTS AN ANALYZED NORMATIVE TEXT AND SEVERAL ANALYZED BUT TRANSLATED READINGS.
