Explanation: section 4.3 in Brief History of Poetry in the Meter paragraph it states "Meter is the Greek word for measure. In poetry, we measure by the foot. A poetic foot is composed of two or more accented or unaccented syllables, and the different types of feet describe different patterns of stressed (accented) and unstressed (not accented) syllables. The most common type of foot is the iamb, which consists of an unstressed syllable followed by a stressed syllable".
