Question

Read the quoted lines from the play that follow. What literary device does Shakespeare use to develop Helena's character?

Answer 1

B. Metaphor

A metaphor is a comparison of two things without using like or as. In these lines, Helena is being compared to a spaniel. She is saying that no matter how poorly she is treated by Demetrius, she is devoted to him. 
Imagery is a vivid description that appeals to the senses. Onomatopoeia is a word that sounds like its meaning. Boom, crack, hush all are onomatopoeias.
Personification is giving non-human things human-like traits. The tree branches waved in the wind is one example.
