This concise grammar of Bahasa Indonesia Comprises two major grammatical components, word formation and word classes. In the first part an exposition on non-behavioristic, lexeme-based, and process model morphology is presented. The second part deals with word class classification. The morphological component deals with detailed analysis of all aspects of affixation, compounding, abbreviation, reduplication, back-formation, metanalysis, and combination of processes. The exposition on word classes consists of verb, adjectives, nouns, pronouns, numerals, adverbs, interjection, demonstratives, articles, interrogatives, conjunctions, prepositions, and phatics. The words and their sub-categorization are classified using syntactic criteria. A postscript on syntax and lists of references close the book.
