A Rengay is a type of poem that is a six verse form of linked poetry; collaborative poetry usually written by two to three poets. This style of poetry is a linked form of haiku, with each link able to stand on its own. Rengay poetry is linked, though each link is about a unifying theme. However, while the links are of a unifying topic, each absolutely should be able to stand independently as well.
This style of poem may be written about any one subject which the poets agree upon. To be considered a rengay poem, the piece should be six verse, linked, and should be written by a minimum of two poets. Any deviation from these standard rules would disqualify the poem from being considered as such. Many poets use this form of poetry to convey something about humanity, such as the different aspects of love or death. Because of this, this style of poetry makes wonderful study material, as well as reading material.
