"i served them well / with my noble blade, as was only fitting / small pleasure they had in such a sword-feast / dark things in the sea that are meant to eat me"

what literary device is the phrase "sword-feast"?
a) alliteration
b) characterization
c) kenning
d) exposition

The pharse "sword-feast" is a kenning. Option C is correct.

A kenning is a type of circumlocution, in the form of a compound that utilizes figurative language instead of a more concrete single-word noun.

Kenning generally consists  of two words, and are often hyphenated.

In other words, a kenning is a concise compound or figurative phrase which replaces a common noun.

the answer should be d) he was one of those young thousands who greeted the war with a certain amount of relief, welcoming the liberation from webs of tangled emotion" since it is the best option because it shows his desire to free himself.
