A blank sonnet is a fourteen-line poem that adheres to the traditional structure of the sonnet—octave/sestet or quatrains/couplet, volta, thematic development—but deliberately omits end-rhyme, relying instead on meter, enjambment, and rhetorical shape to fulfill the form’s expectations; this hybrid challenges the necessity of rhyme in sonnet writing while preserving the form’s intellectual and emotional architecture, as seen in modernist experiments by poets like Robert Frost or contemporary practitioners reimagining the sonnet’s possibilities.

Sonnet-length poem (14 lines) in blank verse rather than rhymed. Maintains structural integrity without sonic closure. Related: nonce form, blank verse. Tests whether form depends on rhyme or line count.
