In a poem addressed to his young son, S.T. Coleridge explains each of the most common metrical feet: the trochee, spondee, dactyl, iamb, anapest, amphibrach, and amphimacer. Whew! Best part is: he both defines these terms and demonstrates them within the line. This brief and clever learning experiment takes up the first stanza.
In the second stanza, Coleridge tells his son Derwent everything he needs to become a famous poet: love for nature, a warm heart, and of course meter. Becoming a good poet will help him win his father's and God's love. But wait, Coleridge already loves his son a ton already. Aw, how sweet.
