This book has been produced to meet the needs of those learning under the structure of the Languages Ladder programme of the UK Department for Children, Schools and Families. Unlike some other coursebooks this book teaches Cornish in a "can-do" way, and does not expect students to know the finer points of Cornish grammar from the beginning. The course starts with the basics - which are all presented in a friendly and accessible way. This course is aimed at the Breakthrough level of the Languages Ladder. This consists of three stages and Skeul an Tavas is divided into three parts corresponding to those stages. The book contains many practical examples of natural Cornish. Students can practise adding to what they have learned by constructing further examples with the use of a dictionary. Skeul an Tavas contains a complete glossary of all the Cornish words found in the book. The illustrations will help students to learn the meaning of many Cornish words without reference to English. Skeul an Tavas will help any student to acquire Cornish as a spoken language for everyday use. This book uses Standard Cornish ("Kernowek Standard" or "KS") spelling, which is a development of the Cornish Language Partnership's "Standard Written Form", correcting a number of identified problems. Kernowek Standard is more logical, simpler, and easier to learn, and is closer to the forms of the historical language.
