Which of the following is NOT typically classified as a type of poetry?

Allegory is a narrative technique rather than a type of poetry. It usually encompasses entire stories or texts that convey deeper meanings through symbolic figures, actions, or events. Allegories can be found in various literary forms, including novels or short stories. In contrast, lyric poetry, epic poetry, and free verse are all specific forms of poetry characterized by their structure, themes, and expressive qualities. Lyric poetry focuses on personal emotions and thoughts, epic poetry narrates grand tales often tied to cultural myths and history, and free verse removes traditional meter and rhyme scheme, allowing more freedom in expression. Thus, classifying allegory as a type of poetry is incorrect, making it the right choice in the question.
