Learn Romani: Das-duma Rromanes

This book is a great mix of old-style grammatical explanations and cultural hints related to the Romani language. Very well presented, very well analyzed, very comprehensive!
The grammar is based on the one of the Kalderash dialect, the clearest and most widely spoken amongst Romanis all around the world, but the last chapters include information about other dialects as well, and long comparative lists of words to learn the main differences. All this is complemented with a good range of exercises, written and non written, allowing you to practice what you've just learned and to fix in mind all basic concepts.
A great book! I surely advise to purchase!
