thy heart by george macdonald make not of thy heart a casket, opening seldom, quick to close; but of bread a wide - mouthed basket, or a cup that overflows. what figure of speech is used when the author compares the heart to a casket? a. simile b. alliteration c. metaphor d. onomatopoeia what is the overall message in the poem?
Answer
Brief Explanations:
A metaphor is a figure of speech that makes an implicit, implied, or hidden comparison between two things that are unrelated but share some common characteristics. Here, the heart is directly compared to a casket without using "like" or "as" (which would make it a simile). Alliteration is the repetition of initial consonant sounds, onomatopoeia is the use of words that imitate sounds, neither of which apply here.
Answer:
c. metaphor
