Originally composed and transmitted orally, skaldic poetry utilizes alliterative verse, kennings, and various metrical forms. In skaldic poetry, the name Eir is frequent in kennings for women. These he distinguished from circumlocutions, "kend heiti" "qualified terms" (i.e. kennings). According to this view, all kennings are formally compounds, notwithstanding widespread tmesis. Another factor aiding comprehension is that Old Norse kennings tend to be highly conventional. He then goes on to discuss various poetic metaphors known as "kennings". Other features of vernacular poetry of this time include kennings, internal rhyme, and slant rhyme. Alternate names (kennings) for the female German Nixe are Rhine maidens () and Lorelei. Only a few examples of Odin's kennings are given here. Kennings, and even whole clauses, can be interwoven. Some recent English writers have attempted to use approximations of kennings in their work. Kennings of up to seven elements are recorded in skaldic verse. Kennings are also a significant technique in "Beowulf". Kennings are strongly associated with Old Norse-Icelandic and Old English poetry.
