Vowel alternation in lithuanian and latvian deverbative nouns: flexion and consonant suffix derivatives

Vowel alternation in Lithuanian and Latvian deverbative nouns: flexion and consonant suffix derivatives The object of this research work is Lithuanian and Latvian deverbative nouns: flexion and consonant suffix derivatives with vowel alternation. The significance of this paper is reflected by the comparison of two Eastern European languages – Lithuanian and Latvian. Vowel alternation in verbalized nouns – inflections and consonant suffixes are being investigated in these languages. The aim of this work is to discuss Lithuanian and Latvian deverbative nouns: flexion and consonant suffix derivatives in synchronic and diachronic aspects and to find similarities and differences between these two Baltic languages. The first task was to collect Lithuanian and Latvian deverbative nouns: flexion and consonant suffix derivatives and to classify them by type of vowel alternation. The second task was to compare morphonological alternations which are specific in Lithuanian and Latvian. Results after the investigation: 1. Morphological vowel alternation in consonant suffixes and deverbative nouns made by changing inflections is more frequent in Lithuanian than in Latvian. In 46,2% (224) out of 485 Lithuanian derivatives experience vowel change, meanwhile only 12,6% (37) out of 294 Latvian derivatives experience the change. 2. Common examples of overlapping derivatives change, we have 12, 7 of them going on a <e change. a <e change is the most common seen in Lithuanian language derivatives - 90 examples of this change, in Latvian language – 5 of this change in derivatives and it is also attributed to the frequently occurring types of change. It is therefore concluded that a <e change is common and the most common in both languages. 3. Lithuanian language consonant suffixes and endings derivatives formation model is much more productive than the Latvian language, because in Lithuanian languagenconsonant suffixes number (485) is even higher than the Latvian language in which the samples to review the more (found 294). 4. The most common quantitative change in the Lithuanian language is ai<i and y<i and qualitative – a<e. Latvian language to one of these quantitative change: ai<i, ā<e, ā<a and i<ai.. Qualitative change the most common type of qualitative change is a
