ONOMASTIC LEXICOGRAPHY WITHIN LINGUISTIC-AND-ECOLOGICAL APPROACH

In the study linguistic-and-ecological approach is used for describing the reference book of regional toponyms The Names of Settlements in the Volgograd Region as a lexicographic issue. Dictionary entry zones are described and the most complex issues of their compilation are indicated. The authors have characterized the entry zone The Degree of Name Uniqueness within the Region, represented in the onomastic dictionaries for the first time. The four successive stages in oikonym uniqueness gradation have been identified, that enables making adjustments to the directories and reference books while nominating settlements. The zone of the dictionary entry Syntactic Characteristic of the Head Unit in Combination with the Appellative, the introduction of which is stipulated by the variability of such combinations in speech practice, contains information about case parallelism between the oikonym and the appellative, or its absence. The zone of the dictionary entry Ottoponymic Derivatives of the Vocabulary Unit reveals the possibility of forming relative adjectives and nouns naming the inhabitants of a particular locality. Dictionary entries in the reference book are drawn up taking into account the linguistic-and- ecological criteria developed by the authors for the toponymic names.
