What is the figurative language used in Sonnet 130?

Figurative language is any kind of language where the Words do not mean precisely (literally) what they say.

Shakespeare's Sonnet 116 is not an obvious sonnet to choose for examples of figurative language (for a number of reasons): but when Shakespeare says that he does not want to 'admit impediment' to Love, that is an example of figurative language. He does not literally mean that he worries that Love might stumble over something, he just says that he is not going to criticise true love in any way.

Similarly, later, when he calls love a 'star to every wandering bark' he does not literally mean that Love appears in the night sky; he means that love is how we navigate our lives - so this is also figurative language.

There is more figurative language in this sonnet, but now that you know what you are looking for - you will probably be able to find your own.
