What does iambus mean?
An iambus is a basic unit of meter consisting of two syllables: one unstressed syllable followed by one stressed syllable. Its rhythm can be represented as da-DUM or x/, and it is the dominant foot in much English verse, including blank verse and iambic pentameter. The word is especially useful for discussing how poets create rhythm, stress, and movement in poetry. In modern English discussions, the shorter and more familiar term “iamb” is often used instead. “Iambus” remains valuable in formal metrical terminology, especially when precision is needed or when comparing different kinds of metrical foot with terms such as trochee and spondee.

Where does iambus come from?
The word comes from Greek iambos, an ancient term for a metrical foot consisting of a short syllable followed by a long one. Greek iambic poetry took its name from this metrical pattern and was associated especially with satirical verse. English borrowed the term through Latin, where iambus was used in discussions of classical meters.
