I have read somewhere that it is typical of poems such as Nibelungenlied to use a figure of speech which in fact merges two phrases into one by the mean of a common word. An example could be the following:
And then I ate the apple was red as blood
A proper example of this can be found in Nibelungenlied (Adventure 20, 1184, 1-2), where we have
Ortwin von Mezze | ce Rvedgeren sprach
Ortwin von Metz | to Rüdiger said
So, is there a name for this figure of speech? Is it a typical figure of other archaic poems such as Beowulf or am I confusing?
