-- by parts of speech, with Swahili names for them (Kiima = noun, e.g.). A more "insider" perspective on the language; for instance, the "subjunctive" or "polite imperative" is described as "the Wishing Form" in this book.
TEACH YOURSELF SWAHILI, A Complete Course for Beginners,
NTC Publishing Group, Chicago, 1996.
Dialogues followed by good explanation; cassettes available. This book would be my recommendation for someone who wants to acquire a working knowledge of the language.
VocabuLearn tapes, Swahili/Kingereza -- words and phrases, two 90 minute tapes.
My first contact with Swahili was through the Lonely Planet language survival guide. For less than $3 (!), all the tourist probably really wants to know.
