Blank verse is a type of poetry that is written in unrhymed lines of iambic pentameter. This means each line typically has ten syllables, alternating between unstressed and stressed syllables. It is often used in English dramatic and narrative poetry, allowing for a natural flow of speech while maintaining a rhythmic structure. Many famous playwrights and poets, such as William Shakespeare and John Milton, have utilized blank verse in their works. Its flexibility makes it suitable for both serious themes and everyday conversation, making it a popular choice for expressing complex ideas and emotions in a lyrical form.
