Sonnet 116 by William Shakespeare: poem analysis & meaning

Sonnet 116 the full poem, lines numbered

Let me not to the marriage of true minds

Admit impediments. Love is not love

Which alters when it alteration finds,

Or bends with the remover to remove:

5O, no! it is an ever-fixed mark,

That looks on tempests and is never shaken;

It is the star to every wandering bark,

Whose worth’s unknown, although his height be taken.

Love’s not Time’s fool, though rosy lips and cheeks

10Within his bending sickle’s compass come;

Love alters not with his brief hours and weeks,

But bears it out even to the edge of doom.

If this be error and upon me prov’d,

I never writ, nor no man ever lov’d.

The poem in 60 seconds

“Let me not to the marriage of true minds / Admit impediments” opens a sonnet often read at weddings. It is less a love letter than a definition: love is a fixed point that storms and time cannot move. Watch how much of the poem says what love is not, and how the couplet dares anyone to prove it wrong.

The poem opens, “Let me not to the marriage of true minds / Admit impediments,” meaning the speaker will not accept that anything can stand in the way of a union between faithful minds. Love is not love, he says, if it changes when it finds change in the other person, or if it bends and goes away when the other person goes away. No, love is a fixed mark that looks on storms and is never shaken. It is the star that guides every wandering ship, a star whose height sailors can measure but whose true worth is unknown. Love is not the plaything of Time, even though rosy lips and cheeks fall within the sweep of Time’s curved sickle. Love does not change with Time’s brief hours and weeks. It lasts to the edge of doom, the end of the world. The couplet makes a wager. If this is wrong and can be proved against him, then he never wrote anything, and no man ever loved.

Speaker & situation

SpeakerA speaker who sounds sure of himself, laying down a definition of true love. He is often identified with Shakespeare, and line 14 (“I never writ”) presents him as a writer, but it is safest to treat the voice as a speaker.

Addressed toNo listener is named, and the poem never says “thou.” It reads like a statement made to anyone who doubts that love can last. It sits among Sonnets 1 to 126, which many readers take to concern a young man.

OccasionNo event is named. The first lines borrow the language of a wedding, which is why the sonnet is so often read at marriages, but the “marriage” here is a union of “true minds.” The date it was written is not known.

ToneFirm and declarative, like an oath or a legal argument. Line 5 breaks out with feeling, “O, no!”, and the couplet ends on a confident challenge.

Form & sound

FormShakespearean sonnet; three quatrains and a closing couplet, fourteen lines in all, printed here as a single block.

MeterIambic pentameter. “Ever-fixed” in line 5 needs “fixed” said as two syllables to fill the line. Lines 6 and 8 end with an extra unstressed syllable (“shaken,” “taken”).

Rhyme schemeABAB CDCD EFEF GG: minds / finds, love / remove, mark / bark, shaken / taken, cheeks / weeks, come / doom, and the couplet prov’d / lov’d. Love / remove, come / doom and the couplet’s prov’d / lov’d are near rhymes to a modern ear.

StructureThe first quatrain says what love is not. The second says what it is, through two images of steadiness, a sea mark and a star. The third sets love against Time. The couplet stakes everything on the argument.

SoundWords repeat in changed forms: “alters” and “alteration” (line 3), “remover” and “remove” (line 4), “bends” (line 4) and “bending” (line 10). The echoes show change happening around love while love itself stays put.

Line by line what each part says and does

1

Lines 1–4

What love is not

The speaker refuses to admit any obstacle to the union of true minds. Love is not love if it changes when it finds change, or bends away when the other person moves away.

How it worksThe opening borrows from the marriage service, where the congregation is asked about impediments to a wedding. The definition begins in the negative, clearing away false kinds of love before naming the real one.
2

Lines 5–8

The mark and the star

No, love is a fixed mark that looks on storms and is never shaken. It is the star that guides every wandering ship, whose height can be measured though its worth is unknown.

How it worksBoth images come from sailing. A sea mark is a landmark or beacon that guides ships, and sailors found their position by measuring a star’s height. Love is what the lost steer by, and its value is beyond measuring.
3

Lines 9–12

Love against Time

Love is not Time’s fool, even though youthful beauty falls within the sweep of Time’s curved sickle. Love does not change with Time’s brief hours and weeks. It lasts to the edge of doom.

How it worksTime appears as the reaper with a sickle, cutting down rosy lips and cheeks. The poem grants that beauty will be cut down but insists that love is something else, and it will last until the end of the world.
4

Lines 13–14

The wager

If this is error and it can be proved against the speaker, then he never wrote, and no man ever loved.

How it worksThe couplet uses the language of a trial (“error,” “upon me prov’d”). Since he has plainly written, and people have plainly loved, the claim cannot be disproved.

The turn

Lines 13

This sonnet has no sharp change of mind. Lines 1 to 12 build one definition, first saying what love is not, then what it is, then how it stands against Time (the move to Time at line 9 is the nearest thing to a volta). The clearest turn comes at line 13, where definition gives way to a dare: “If this be error and upon me prov’d.”

Literary devices with line numbers

Allusion

Lines 1 and 2, “the marriage of true minds / Admit impediments,” echo the marriage service in the English Book of Common Prayer, which asks whether anyone knows of an impediment to the marriage. The speaker answers that for true minds there is none.

Definition by negation

Lines 2 to 4 define love by what it is not: “Love is not love / Which alters when it alteration finds.” Line 9 does it again, “Love’s not Time’s fool,” and line 11, “Love alters not.” The negatives rule out every false version of love.

Polyptoton

The same root appears in different forms: “alters” and “alteration” in line 3, “remover” and “remove” in line 4. The word shifts shape while the idea it describes, change, is exactly what true love refuses.

Metaphor

In line 5 love is “an ever-fixed mark” that looks on tempests unshaken, and in line 7 it is “the star to every wandering bark,” a bark being a ship. Line 8 adds that sailors can take the star’s height but not know its worth, so love guides people without being fully understood.

Personification

In lines 9 and 10 Time is a figure with a “bending sickle,” the reaper who cuts down “rosy lips and cheeks.” Love is not his “fool,” meaning his plaything or jester.

Double negative

Line 14, “I never writ, nor no man ever lov’d,” stacks negatives for emphasis, which was normal in Shakespeare’s English. The line clinches the wager: both things it denies are obviously true.

Themes in Sonnet 116

ConstancyLove and timeLove as a guideCertainty and proof

Constancy

The sonnet’s one claim is that true love does not change: not when the beloved changes, not when the beloved goes away, not in storms and not over time.

Love and time

Time will cut down youthful beauty, and the poem admits it in lines 9 and 10. It separates love from beauty so that love can survive what beauty cannot.

Love as a guide

The mark and the star in lines 5 to 8 are things sailors steer by. Love is pictured as a fixed point that gives direction to people who are lost or in danger.

Certainty and proof

The poem argues like a lawyer, ending with “error” and “prov’d.” It presents its definition as something that could be tested, and dares the reader to try.

Images and symbols

The ever-fixed mark

A sea mark, a landmark or beacon that guides ships, stands in line 5 for love that stays steady while storms rage around it.

The star

The guiding star of line 7 is usually taken to be the North Star, which sailors navigated by. Its height can be measured but its worth cannot, like love.

The sickle

Time’s “bending sickle” in line 10 stands for aging and death, which cut down youthful beauty but, the poem insists, not love.

Tensions

Love vs. time. Time has power over bodies and beauty, and the poem grants it that. The conflict is settled by declaring love outside Time’s reach “even to the edge of doom.”

Ideal vs. experience. The poem states an ideal with total confidence. Some readers hear the insistence as a sign of doubt: a speaker who needs to swear this hard may have seen love change.

The ending

How Sonnet 116 ends, explained

The couplet turns the definition into a bet: “If this be error and upon me prov’d, / I never writ, nor no man ever lov’d.” “Error” and “prov’d” are words from a courtroom, where a claim is tested and found false. The speaker stakes two things on his definition, his own writing and the whole history of human love. Both plainly exist: the poem is proof that he wrote, and people obviously have loved. So the argument cannot be proved wrong, and the couplet closes the case. Most readers take this as a confident, even triumphant, ending that seals the poem’s claim. Some find it a little too neat, a trick of logic rather than evidence, since the fact that people have loved does not prove their love never changed. Others hear something anxious under the confidence. The poem spends most of its lines saying what love is not, as if answering someone, perhaps the speaker himself, who has seen love alter. On that reading the couplet’s certainty is partly a way of holding on to an ideal. Either way, the ending turns an ideal into a dare that the reader is invited to answer.

“Let me not to the marriage of true minds / Admit impediments.”

Lines 1–2. The famous opening borrows the wedding service’s question about impediments and refuses to allow any for a union of faithful minds.

“Love is not love / Which alters when it alteration finds,”

Lines 2–3. The definition begins in the negative. The echo of “alters” and “alteration” makes the point: love that answers change with change is not real love.

“Love’s not Time’s fool, though rosy lips and cheeks / Within his bending sickle’s compass come;”

Lines 9–10. Time is the reaper with a sickle. Beauty falls within its sweep, but love is not Time’s plaything.

“If this be error and upon me prov’d, / I never writ, nor no man ever lov’d.”

Lines 13–14. The wager. Since the speaker has written and people have loved, the argument cannot be disproved.

Common misreadings

MythThe poem is about a wedding between a husband and wife.

ActuallyIt borrows the language of the marriage service, and it is often read at weddings, but the “marriage” in line 1 is a union of “true minds.” The poem defines faithful love in general and never mentions a bride, groom or ceremony.

Myth“Love’s not Time’s fool” means love is not foolish.

ActuallyA “fool” here is a jester or plaything, someone at another’s mercy. The line means love is not at Time’s mercy, even though Time’s sickle cuts down youthful beauty (lines 9–10).

MythThe couplet shows the speaker is unsure.

ActuallyThe couplet is a dare. It says that if the argument is wrong, then he never wrote and no man ever loved, both obviously false, so the argument must stand. Some readers hear anxiety beneath it, but the statement itself is a confident wager.

Answer

Explain it like I’m 12

This poem tries to explain what real love is. The speaker says real love does not change when the other person changes or goes away. He says it is like a tower on the shore that guides ships and stands firm in a storm, or like the star that sailors use to find their way. Time makes people old and wrinkled, but real love does not fade with time. At the end he makes a bet. If he is wrong, then he never wrote anything and nobody ever loved, and we know both of those are not true.

Compare & connect

A Valediction: Forbidding Mourning

John Donne

Donne also describes a love of minds that does not depend on being together, and he pictures it with an instrument, a drawing compass, where Shakespeare uses a sea mark and a star.

Sonnet 18

William Shakespeare

Both sonnets set something against Time. Sonnet 18 claims a poem can preserve beauty; Sonnet 116 claims love outlasts beauty altogether.

How Do I Love Thee? (Sonnet 43)

Elizabeth Barrett Browning

Another famous sonnet that tries to define love. Barrett Browning counts the ways she loves; Shakespeare lists what love is and is not.
