Fixed form  A poem that may be categorized by the pattern of its lines, meter, rhythm, or stanzas. A sonnet is a fixed form of poetry because by definition it must have fourteen lines. Other fixed forms include limerick, sestina, and villanelle. However, poems written in a fixed form may not always fit into categories precisely, because writers sometimes vary traditional forms to create innovative effects. See also open form.
