In scansion, what is the standard description of an iamb?

• A. An unstressed syllable followed by a stressed syllable
• B. A stressed followed by an unstressed
• C. A syllable with equal stress
• D. A long vowel sound only

Answer: (A)

An iamb is the unstressed-stressed two-syllable unit, the da-DUM rhythm that English verse commonly uses. This description fits because it mirrors natural speech and gives poets a steady beat to pattern lines, especially in iambic pentameter with five iambs per line. When you read aloud, the first syllable is lighter and the second carries the emphasis, as in to-DAY or be-COME. The defining feature is the stress pattern, not vowel length. Other patterns would describe a trochee (stressed-unstressed), a spondee (two stressed), or a pyrrhic (two unstressed), and a long vowel by itself doesn’t specify the beat. So the best description is the unstressed followed by a stressed syllable.
