Poets' feet is a term used to describe the rhythm of a poem, specifically the pattern of stressed and unstressed syllables. The two most common types of poetic feet are iambs and iambi. An iamb is a metrical foot consisting of two syllables, with the first syllable unstressed and the second syllable stressed. An iambi is similar, but with three syllables, with the first two syllables unstressed and the third syllable stressed.
