The present study concentrates on specific linguistic aspects in traditional Estonian poetic texts. Focusing on the verse structure of the traditional folk song of Vana kannel and the individually edited and authored epic poem Kalevipoeg , different aspects of the length of verse lines, of the words included in these verses, and of the relation between verse and word length shall be analyzed, aiming to study verse variability in detail. Given there are specific rules of verse and word length organization, as well as of regular relations between them, sequences of words with different length, resulting in different verse types, are focused. Theoretical and empirical evidence is provided that, in addition to existing regularities, verse variability, too, follows specific rules which can be modelled in terms of a diversificational process.

诗歌多样化：瓦纳犬和卡列维堡的诗歌类型的频率和变异

本研究集中在爱沙尼亚传统诗歌文本中的特定语言方面。着眼于瓦纳·坎纳尔（Vana kannel）传统民歌的诗句结构以及个人编辑和创作的史诗诗《卡列维波格》，诗句行长，这些诗句中所含单词的不同方面以及诗句与单词长度之间的关系应在各个方面进行分析，旨在详细研究诗歌的变异性。给定特定的经文和单词长度组织规则，以及它们之间的规则关系，着眼于具有不同长度，导致不同经文类型的单词序列。提供的理论和经验证据表明，除了现有的规律外，诗歌的变异性也遵循可以根据多元化过程建模的特定规则。
