What are an iamb?

An iamb is a metrical foot used in poetry that consists of two syllables: the first syllable is unstressed, followed by a stressed syllable (da-DUM). It is commonly found in English verse, notably in iambic pentameter, which features five iambs per line. This rhythmic pattern creates a natural flow and is often used by poets like Shakespeare and Milton. The iamb's structure contributes to the musicality and emotional depth of a poem.
