Pentameter
From Encyclopedia Jr, free information reference for Kids
In poetry, a pentameter is a line of verse consisting of five metrical feet. Iambic pentameter is one of the most commonly used meters in English, used extensively by William Shakespeare, John Milton, and William Wordsworth, to name but three of the many poets who have employed it.
The Dactylic Pentameter is found in elegiac poetry as the second in a couplet consisting of a Dactylic Hexameter and a Pentameter (which is called an elegiac distich).
