: a line of verse consisting of five metrical feet
Did you know?
In a line of poetry written in perfect iambic pentameter, there are five unstressed syllables, each of which is followed by a stressed syllable. Each pair of syllables is a metrical foot called an iamb. Much of the greatest poetry in English has been written in iambic pentameter; Chaucer, Shakespeare, and Milton used it more than any other meter. Robert Frost's line "I'm going out to clean the pasture spring" is an example of it; his "And miles to go before I sleep" is instead an example of iambic tetrameter, with only four accented syllables.
