This book covers topics related to linguistic morphology, a course designated as core in most universities worldwide. At least all mechanisms of word-creations have been discussed in this volume. However, much effort is devoted to major word-building processes: affixation (derivation and inflection), reduplication, borrowing and compounding. In order to offer theoretical orientations to morphological data analyses, three theories have been incorporated at the end of the book: lexical morphology theory, templatic (autosegmental) theory and optimality theory.
