Blank verses, also known as unrhymed iambic pentameter, is a popular poetry form used by many famous poets like William Shakespeare, John Milton, and William Wordsworth. However, if you're trying to add some variety to your verse, there are numerous synonyms to explore. Some of them include free verse, which allows for more flexibility in terms of meter and rhyme, terza rima, which uses a three-line rhyming scheme, and haiku, which follows a 5-7-5 syllable structure. Other alternatives include sonnets, sestinas, and villanelles, all of which offer different patterns and styles to experiment with. So, if you're looking to expand your poetry skills, don't be afraid to step outside of the blank verse comfort zone and try something new.
