Question

An example of kenning for king hrothgar from beowulf is

Answer 1

 Simply put, a kenning is a way of describing something without actually mentioning what it is. A metaphor, if you like. 

For instance,  

Slaughter dew = Blood 
Sleep with the sword = Death 
Swan of blood = A Raven 

Therefore your answer must be A or B 

Although I'm not completely certain, I would guess that King hrothgar is a 'Shielder of shield bearers', as he is a king. 

Sorry I couldn't be of more help. 

Good luck.
