Two invented sonnet forms were found in Pathways for a Poet by Viola Berg 1977. This book was written for teachers with contributions by teachers. The various forms were offered as learning exercises.
• The Illini Sonnet uses iambic tetrameter as well as pentameter to complete the quatorzain. Inventd by Nel Modglin who probably is connected to the University of Illinois in some way since “Illini” is the nickname connected to the school.
The Illini Sonnet is:
○ a quatorzain.
○ metered, iambic – L1,L4,L5,L8,L9 and L12 are tetrameter and L2,L3,L6,L7,L10,L11,L13 and L14 are pentameter.
○ rhymed, abcabcdbcdecee.
