Desky Kernowek, a complete guide to Cornish, is aimed at both beginners and the more advanced student. The book uses Standard Cornish, an orthography that is at once authentic and wholly phonetic. The whole grammar of Cornish is discussed in Desky Kernowek and both Middle and Late Cornish variants are accommodated. All points of grammar and vocabulary are exemplified by instances from the traditional texts in the original spelling. A key to the exercises is given at the end of the book for those learning Cornish by themselves. Desky Kernowek contains a comprehensive phrase-book taken exclusively from traditional Cornish. It also contains a detailed discussion of initial mutation, and a section on verbal usage. The book contains both Cornish-English and English-Cornish glossaries and a full index of subjects. -- The section on pronunciation and spelling was written by Michael Everson, a leading expert on writing systems. Professor Nicholas Williams, the author of Desky Kernowek, has been described by Philip Payton, Director of the Institute of Cornish Studies of the University of Exeter, as "the foremost scholar of the Cornish language".
