Final answer:
Free verse is the term for poetry that has no rhyme and mimics the natural rhythm of regular speech, offering freedom in expression and relying on irregular use of metrical patterns and occasional rhyme for structure.
Step-by-step explanation:
The term for poetry that does not have rhyme and is written in the natural rhythm of regular speech is called free verse. Unlike traditional poetry which relies on specific metrical patterns and rhyme schemes, free verse poetry offers the poet more freedom in expression.
Free verse poetry can still employ metrical patterns and rhyme, but it does so irregularly, instead depending on thematic, syntactic, or semantic repetition to provide structure and coherence.
Some well-known poets associated with free verse include Walt Whitman and modern poets, who often chose to write in this form because of its flexibility and closeness to natural speech.
Notable free verse works can vary in stanza length, from a couplet (a two-line stanza) to a sextain (a six-line stanza), and may include occasional internal rhyme, but will not typically maintain a specific poetic form throughout the entirety of the piece.
