After thoroughly studying the 1211 land survey of the Abbey of Tihany, the author decided to continue her work along the general lines of Hungarian historical linguistic research and disclose even more exact information about the Hungarian language and its users of the decades following the Hungarian conquest of the Carpathian Basin. This linguistic record of outstanding philological significance contains more than 2,000 Hungarian elements (approximately 200 toponyms and about 2,000 anthroponyms) from the Zala and Somogy coast of Lake Balaton, from the Tolna-Bodrog area along the Danube, as well as from the Torontál section of the river Tisza.

The book of nearly 250 pages is divided into four voluminous units, including chapters of a theoretical character and entries with a profound analysis of Hungarian place names. In the first chapter the author discusses the linguistic importance of the charter, and argues for the necessity of the linguistic (onomastic) description of this remarkable language monument. The second chapter contains the Latin text and the Hungarian translation of the charter, with some further details of philological nature. In the third, central chapter the author presents a complex analysis of those Hungarian toponyms which appear in the Tihany land survey. The corpus is examined from the following aspects. 1. A historical-etymological analysis of the linguistic data, completed with peculiarities of their historico-phonetic development, orthographic features and facts of interes in their linguistic history. 2. Localisation, i.e. the identification of the toponyms with particular areas, with complementary information about their, occurrence in earlier or later documents. 3. Its connection with other sources especially with the 1055 founding charter of the Abbey of Tihany, the earliest authentic Hungarian written record. 4. The relation between the Hungarian place names and the Latin text. In the fourth, comprehensive chapter, the author touches upon the general questions of the Tihany land survey as a linguistic record, summing up the methods of how the Hungarian place names were integrated into the Latin text, local features of the ways the toponyms were recorded together with their onomatosystematical peculiarities.
