In Shakespeare's 9th sonnet, what are some devices of language used?Like symbolism, irony, allusion, imagery, diction, allusion, etc.

I respectfully disagree with the previous poster. The speaker in the sonnet is not the one who chooses to remain single and childless. The speaker is addressing another man, the "thou" (or "you") in the poem. As I read the poem, the speaker seems to be saying that the man he's talking to is too beautiful to die without first having children. To die childless would be a crime: "No love toward others in that bosom sits / That on himself such murderous shame commits."

The line "The world will wail thee, like a makeless wife" introduces at least two devices. The first, a simile, is quick and easy; it's the comparison between "world" and "wife" that begins with the word "like." The other device is personfication, the world is turned into a human-like figure, one that can experience and express emotions. This personification is the most fully developed literary device in the poem.
