This chapter offers an analysis of the language, metres and forms of Old Norse poetry. It begins with a brief account of Old Norse language and related languages, and then considers the specialized language of Old Norse poetry, with its distinctive lexis and syntax, especially in skaldic verse. Compound words and kennings are discussed, followed by analysis of alliteration and rhyme in Old Norse poetry. The stanzaic form of eddic verse is described, with a detailed account of its main metres and scansions based on Sievers’s ‘five types’. Next, the forms of skaldic poetry are outlined, with an account of lausavísur or ‘loose stanzas’, and the different kinds of stanza sequences, such as the flokkr and the drápa. The primary metre of skaldic verse, dróttkvætt or ‘court metre’, is defined and illustrated, together with some of its many variations, and then attention turns to the rímur, a later form of rhyming and alliterative poetry in extended sequences of stanzas. The chapter concludes with a discussion of how metrical considerations may have affected scribal practice in the Middle Ages and have impacted editorial processes by modern scholars.
