Answer:
kenning
Step-by-step explanation:
Kenning is a literary device widely used in medieval literature in Nordic countries. This device is used to replace words of direct and denotative meaning for words of figurative meaning.
We can perceive kenning in Beowulf's speech when he says "The shelterer of warriors and your people’s loved friend" instead of using the word king, thus translating a more poetic and connotative language.
