A choriamb is a metrical foot that features four syllables: the first and last stress, while the second and third are unstressed. The choriamb is also known in verse as the double iamb. It has its roots in ancient Greek poetry but is also commonly used in modern poetry. Some synonyms for choriamb include "synaphea" and "quaternarius." Other types of metrical feet that are similar to the choriamb include the dactylic and the anapestic. The choriamb can add a musical and rhythmic quality to poetry and is a popular tool for poets who want to create a sense of movement and momentum in their writing.
