This Sonnet 116 summary starts with the short answer. In “Let me not to the marriage of true minds,” William Shakespeare defines true love by what it is not: it does not change when circumstances change, and it does not fade with time, age or distance. Real love is fixed, like a star sailors steer by, and it lasts until the end of life. Read the full text of Sonnet 116 on Poetry Catalog.
Sonnet 116 Summary
Lines 1–4. The speaker refuses to accept that anything can block the union of two faithful minds. “Love is not love,” he says, if it changes when it finds change in the other person, or if it bends to leave when the other leaves.
Lines 5–8. He describes what love is instead. It is “an ever-fixed mark,” like a lighthouse or seamark that faces storms without being shaken. It is “the star to every wandering bark,” the guiding star for every lost ship. Sailors can measure the star’s height, but its true worth cannot be measured.
Lines 9–12. Love is not “Time’s fool,” meaning it is not at the mercy of time. Rosy lips and cheeks may fall within the curve of Time’s sickle, but love does not alter with “his brief hours and weeks.” It lasts “even to the edge of doom,” to the end of the world or of life.
Lines 13–14. The couplet is a bold guarantee: if he is wrong, then he never wrote anything, and no man ever loved. Since he has written and people have loved, he must be right.

Themes
Constancy. The heart of the poem is faithfulness. True love does not depend on beauty, youth or the other person’s behavior.
Love against time. Time destroys looks and youth, but the poem places love outside time’s reach.
Definition by negation. Much of the sonnet says what love is not: not altering, not bending, not Time’s fool. By ruling things out, it narrows down what love really is.
Certainty. The final couplet stakes everything on the argument. It reads like an oath.
Key Lines Explained
Let me not to the marriage of true minds
Admit impediments.
“Impediments” are obstacles to a marriage. The wording echoes the traditional English wedding service, which asks if anyone knows a reason two people should not be married. That is one reason the sonnet is so often read at weddings.
Love is not love
Which alters when it alteration finds,
The repetition of “alters” and “alteration” is the point. Love that changes because the other person has changed was never love.
It is the star to every wandering bark,
Whose worth’s unknown, although his height be taken.
A “bark” is a small ship. Sailors navigated by measuring a star’s height above the horizon. We can use love to steer by, but we cannot calculate its value.
If this be error and upon me prov’d,
I never writ, nor no man ever lov’d.
A playful, unbeatable argument. The poem itself is proof that he wrote, so his claim must stand.
Form, Meter and Rhyme
Sonnet 116 follows the Shakespearean pattern: three quatrains and a couplet, rhyming ABAB CDCD EFEF GG, in iambic pentameter. Some rhymes, such as “love” and “remove,” and “come” and “doom,” are eye rhymes or near rhymes to modern ears; pronunciation has shifted since 1609.
Line 2 breaks in the middle, “Admit impediments. Love is not love,” which makes the reader pause just before the definition begins. The sea imagery of the second quatrain and the image of Time with a sickle in the third give the argument concrete pictures.
Unlike many sonnets, this one has no sharp change of direction at line 9. Instead the argument builds steadily, quatrain by quatrain, from refusal to image to time, until the couplet seals it. The effect is of a mind already made up.
