The term 'Summary Stanza' refers to a type of poetic form that is used to bring closure to a poem. It is usually the last stanza of a poem and serves to summarize the main points of the poem. The term 'Envoi' is also used to refer to this type of stanza, which is derived from the French word for 'sending off'. This type of stanza is often used to provide a moral or message to the reader, and can be seen as a way of saying goodbye to the poem.
