What does Iambic pentameter specifically refer to?

Iambic pentameter specifically refers to a line of poetry that consists of ten syllables, arranged in a particular rhythmic pattern. Specifically, it is made up of five iambs, which are metrical feet consisting of an unstressed syllable followed by a stressed syllable (da-DUM). This pattern creates a natural rhythm that closely mimics everyday speech, making it a popular choice among poets, especially in English literature. Each of the five iambs contributes to the total of ten syllables, ensuring the line maintains the characteristic structure of iambic pentameter. This rhythmic quality is a hallmark of many famous works, particularly those of William Shakespeare and other playwrights of the Elizabethan era.
