I forgot to include the other sonnet (N. 116). I find it hard to rephrase the last couplet.

1)Sonnets 116 is about love in its most ideal form. True love is to be based on mutual trust and understanding.
2) True love doesn’t change when the situation changes or with the departure of the lover. It is like a lighthouse that is not shaken by the tempests of life.
3) It is like the star that guides every lost ship. Although the star’s true value cannot be calculated, its height can be measured.
4)Love is not at the mercy of Time, though physical beauty is doomed to fall under (??) Time’s sickle.
5) True love bears time out even to the doomsday. Here Shakespeare points out the transience of beauty and time.
6)In the final couplet the poet declares (declared) that, if he is mistaken about the nature of perfect love, then he must take back all his writings on love, truth and faith.
7)If he had judged love inappropriately, then no man has ever really loved.
8)Can you help me rephrase this? What message does he want to convey? “If this be error and upon me proved, I never writ, nor no man ever loved.”

1. Sonnet (singular)

8. If I am mistaken, I have not written nor has any man ever loved.

4. Time should not be capitalized.

The message that Shakespeare wants to convey in the last couplet of Sonnet 116 is that if his understanding of perfect love is proven to be wrong, then he will take back everything he has written about love, truth, and faith, and it would mean that no man has ever truly loved.

To rephrase this, you can say: "If it is proven that my understanding of love is incorrect, then I will renounce all my writings on love and declare that no man has ever experienced true love."

This rephrased statement captures the essence of Shakespeare's message that he is willing to admit his mistake and acknowledge that his writings on love may not hold true if his understanding is proven to be wrong.
