A sonnet is a type of poem that in its traditional form, is written in iambic pentameter (deals with the placement of certain syllables to elicit a certain sound) and typically comprises of fourteen lines much like the poem above.
The poem above is known as Sonnet 18. It was written by William Shakespeare and talks bout how even though the qualities of a summer day might fade, the description of the young man in the poem will live on forever in the poem.
