The décima espinela is a poem written in ten-line verses utilizing isosyllabic rhymed lines. This variant of the décima was invented by Vicente Espinela, whose name lives on in the name of the poem, much like how we refer to sonnets as ‘Shakespearean’ or ‘Petrarchan.’
The décima is a type of ten-line poem that predominantly finds its fame in the Spanish-speaking world. There are many variations of the form throughout Latin America and Spain, including extended 44-line variants, but the most popular would have to be the décima espinela, associated with Vicente Espinel.
