Question

like a pair of thick socks the cold cannot bite through what type of figurative language is used in this line?

Answer 1

It is personification

Answer 2

The figurative language used in this line is called "Personification." This means that an object (in this case, the cold) is given a human-like action.

"cold cannot bite through"

Obviously the cold cannot LITERALLY bite through the thick socks, but the writer uses personification to add depth to the line.
