Sonnet 18
by William Shakespeare · 1609 · 1 min read · 14 lines
Sonnet 18 by William Shakespeare is a poem about a beloved person whose beauty the speaker promises to preserve through verse. It begins by considering a comparison to a summer day, then argues that the beloved is lovelier and more gentle. Summer has flaws: rough winds shake May’s buds, the season ends too soon, and the sun can be either too hot or hidden. These changes lead to a broader claim that all beauty eventually declines through chance or nature. The poem then turns toward a promise: the beloved’s summer will not fade, and death will not claim a final victory. In the closing lines, the speaker explains that the poem will keep the beloved alive as long as people can read it.
What it means, line by line
Lines 1 to 4: The speaker considers comparing the beloved to a summer day but immediately finds the comparison inadequate. The beloved is more beautiful and more moderate. Winds damage the delicate buds of May, and summer lasts too briefly. Calling the season’s span a lease makes its beauty seem temporary and borrowed.
Lines 5 to 8: The sun, described as heaven’s eye with a golden face, can shine too fiercely or become dimmed. These examples widen into a rule: everything beautiful eventually loses beauty. Both accidents and nature’s ordinary changes can cause that loss, making summer an unreliable measure of lasting loveliness.
Lines 9 to 12: The word “But” marks a turn from fading beauty to the speaker’s promise of permanence. The beloved will keep an eternal summer rather than lose beauty. Death becomes a figure who might boast of victory, but the speaker says the beloved will continue through enduring poetic lines.
Lines 13 to 14: The final two lines explain how the promise works: as long as people live and can see, the poem can survive and give the beloved continued life. This is survival through words and readers, rather than a claim that the beloved’s physical body will never die.

Three questions to think about
- How do the poem’s details about wind, sunlight, and seasonal change make summer an imperfect comparison?
- What changes in the speaker’s argument when the poem reaches the word “But” in line nine?
- How do the final two lines explain the kind of life the speaker promises the beloved?
