What defines iambic pentameter in poetry?

• A. A regular pattern of stressed syllables only
• B. A rhythm consisting of five repeating foot syllables
• C. A structure of four stressed syllables per line
• D. A rhyme scheme focusing exclusively on iambs

Answer: (B)

Iambic pentameter is characterized by a rhythm that consists of five pairs of syllables known as "iambs." Each iamb is made up of two syllables where the first syllable is unstressed and the second is stressed, creating a da-DUM pattern. Since "pentameter" refers to the number of feet—specifically five—in a poetic line, the correct answer accurately reflects this essential structure of iambic pentameter. Thus, the description captures the fundamental aspect of the meter used in notable works by poets like Shakespeare and Milton, where the rhythmic flow contributes significantly to the musicality and emotional depth of their verses. The presence of five iambs in a line specifically distinguishes it from other forms of meter that might use different patterns or counts.
