From a publisher blurb:
A complete but simplified instruction in the language of Tsolyánu of the Empire of the Petal Throne by its author and linguist M. A. R. Barker. The work includes chapters on pronunciation, grammar, Engligh-Tsolyáni and Tsolyáni-English vocabularies and an introduction to its script. The most valuable portion for the role player or wargamer of Tekumel will be the guide for travellers, providing useful expressions for travel, lodging, sightseeing, shopping, employment, entertainment, business, religion, health and military activities. A twenty-minute tape cassette on pronunciation of Tsolyáni has also been prepared by Professor Barker.
