These verse forms were elaborated even more into the skaldic poetic form called "dróttkvætt", meaning "courtly metre", which added internal rhymes and other forms of assonance that go well beyond the requirements of Germanic alliterative verse and greatly resemble the Celtic forms (Irish and Welsh). The "dróttkvætt" stanza had eight lines, each having usually three lifts and almost invariably six syllables. Although other stress patterns appear, the verse is predominantly trochaic. The last two syllables in each line had to form a trochee (there are a few specific forms which utilize a stressed word at line-end, such as in some "docked" forms). In addition, specific requirements obtained for odd-numbered and even-numbered lines.
