Iambic refers to a metrical foot used in poetry, consisting of two syllables: the first is unstressed, and the second is stressed. This pattern creates a rhythmic flow that is often found in English verse, making it a popular choice among poets. One of the most famous forms that utilize iambic meter is iambic pentameter, which contains five iambs per line. This structure is commonly associated with the works of William Shakespeare, who effectively employed it in his plays and sonnets, contributing to the musical quality of his language.
