What’s The Easiest Way To Tell If A Poem Is A Sonnet?

by Amy

A sonnet is a poetic form that has endured through centuries, characterized by its strict structure and thematic richness. Traditionally, a sonnet consists of 14 lines, each carefully crafted to adhere to specific rules of meter and rhyme. The sonnet originated in Italy and flourished in English literature, showcasing the poet’s ability to express deep emotions and complex ideas within a compact form.

The historical origins of the sonnet can be traced back to the 13th-century Italian poet Giacomo da Lentini, who perfected the Sicilian octave form. However, it was Petrarch in the 14th century who popularized the sonnet as we recognize it today, with his collection of 366 love poems known as “Canzoniere.” The form was later adapted and popularized in English literature by poets like William Shakespeare, John Donne, and Elizabeth Barrett Browning.

Structural Characteristics

Key to identifying a sonnet are its structural elements:

14 lines: A sonnet always comprises 14 lines, which distinguishes it from shorter forms like the quatrain or longer forms like the epic poem.

Meter: Traditionally written in iambic pentameter, each line consists of five feet, with each foot containing an unstressed syllable followed by a stressed syllable. This rhythmic pattern gives the sonnet its musical quality and flow.

Rhyme Scheme: Sonnets follow specific rhyme schemes that vary between the Shakespearean (English) and Petrarchan (Italian) forms:

Shakespearean Sonnet (ABAB CDCD EFEF GG): Organized into three quatrains (four-line stanzas) followed by a rhymed couplet (two lines), allowing for a clear progression of thought or argument.

Petrarchan Sonnet (ABBA ABBA CDC DCD): Structured into an octave (eight lines) and a sestet (six lines), with a volta (or “turn”) occurring typically between them, signaling a shift in tone or argument.

Divisions and Themes

Sonnets are often characterized by their thematic divisions:

Shakespearean Sonnet: Typically explores a single theme across the three quatrains, developing an argument or perspective, which is then resolved or summarized in the final couplet.

Petrarchan Sonnet: The octave presents a problem or question, with the sestet offering a resolution or response, often incorporating a change in perspective or emotional revelation.

Common themes in sonnets include:

Love: Sonnets are renowned for their exploration of love in its various forms—romantic, unrequited, and enduring.

Beauty and Nature: Poets often use sonnets to meditate on the beauty of the natural world and its relationship to human experience.

Mortality and Time: Sonnets frequently contemplate the passage of time, mortality, and the fleeting nature of life.

Philosophical Reflections: Sonnets can delve into philosophical questions, existential ponderings, and moral dilemmas.

Human Emotions: From joy and ecstasy to sorrow and despair, sonnets capture the depth and range of human emotions with precision and elegance.

Examples and Analysis

Here are excerpts from famous sonnets and their analysis:

Excerpt from Shakespeare’s Sonnet 18:

Shall I compare thee to a summer’s day? (A)

Thou art more lovely and more temperate: (B)

Rough winds do shake the darling buds of May, (A)

And summer’s lease hath all too short a date: (B)

This excerpt from Shakespeare’s Sonnet 18 exemplifies the Shakespearean rhyme scheme (ABAB CDCD EFEF GG) and the poet’s use of vivid imagery and metaphors to convey the speaker’s admiration for the beloved. The structured rhyme scheme and iambic pentameter contribute to the poem’s musicality and coherence, while the final couplet (GG) provides a concluding statement or resolution.

Excerpt from Petrarch’s Sonnet 292:

Italia mia, benché ‘l parlar sia indarno, (A)

Io vo’ con altro schermo insegnare a voi, (B)

Ch’i’ mi truovo in pietà, d’una alma forte (B)

E di capo pensoso, e ‘l mio signore (A)

This excerpt from Petrarch’s Sonnet 292 demonstrates the Petrarchan rhyme scheme (ABBA ABBA CDC DCD) and the thematic division between the octave and the sestet. The volta occurs at the ninth line, where there is a shift from addressing Italy (Italia mia) to contemplating personal emotions and the poet’s inner turmoil.


In conclusion, identifying a sonnet involves recognizing its structural elements—a 14-line format, adherence to meter (typically iambic pentameter), and specific rhyme schemes (Shakespearean or Petrarchan). Understanding these structural characteristics allows readers to appreciate the sonnet’s ability to convey profound emotions and complex ideas within a concise yet powerful framework. For those interested in reading or writing sonnets, focusing on meter, rhyme, and thematic coherence will enhance appreciation and skill in engaging with this enduring poetic form.
