Latgalian Language Training Tool “Vasals!”
In the book Vasals! (2003) Lidija Leikuma & Juris Cibuls use the so-called P. Strod’s spelling of Latgalian, supplemented with elements of everyday language. This book is the first attempt to provide a general overview of the phonetics and grammar of the Latgalian written language (often also in a dialectal) as compared with the Latvian literary language. The book was published by SIA “N.I.M.S.”.
