Argobba belongs to the South Ethio-Semitic language group and is considered to be in critical endangerment. It has at least four speech varieties which are grouped in this book as North Argobba (NA) and South Argobba (SA). This book is a comparative analysis of the grammar and lexicon of the two groups of Argobba considering one speech variety from each. For a better understanding, data from Amharic, the closest relative of Argobba, is considered and compared against the two groups throughout the book.
