What is the term for unrhymed verse that consists of lines of iambic pentameter?

The term for unrhymed verse that consists of lines of iambic pentameter is blank verse. This form is characterized by its structured meter, which follows the pattern of an unstressed syllable followed by a stressed syllable, creating a rhythm that can evoke a natural flow of speech. Blank verse is commonly used in English dramatic and narrative poetry, allowing for a more sophisticated expression while maintaining a musical quality without the constraints of rhyme.

This is distinct from couplets, which consist of two lines that usually rhyme, and free verse, which does not adhere to a specific meter or rhyme scheme. Prose, on the other hand, lacks the rhythmic and metrical structure inherent in blank verse, making it a different form of writing altogether. The defining feature of blank verse is its combination of iambic pentameter with an absence of rhyme, making it a popular choice for playwrights and poets seeking to create a lyrical yet free-flowing narrative.
