Answer:
There are several actually: assonance, anaphora, consonance, enjambment, imagery and metaphor.
Step-by-step explanation:
Anaphora shows the repetition of any expression or word in the first part of verses. Elizabeth has repeated the word "love" in the poem to make her meanings clear.
Consonance shows the repetition of consonant sounds in any verse such as /t/ and /h/ sounds in "thee with the breath."
Enjambment refers to a clause or thought that does not compete at the end of the sentence. instead, it rolls on to the next lines. Elizabeth has used this technique in the poem to emphasize her point.
Imagery is used to make the readers create and imagine what the writer wants to convey. Elizabeth has used this device effectively to make the readers visualize get captivating ways of loving.
Metaphor is making implied comparison between two opposite things. The writer has used love as an extended metaphor in the poem to show how it empowers a person and makes him feel special.
