Expansion: A rhetorical and structural technique involving elaboration, amplification, or development of initial statements, images, or ideas, creating increasing detail, complexity, or intensity. Expansion can occur within lines, stanzas, or entire poems, moving from compressed statement to full exploration. This technique demonstrates poetry's capacity for development and elaboration, showing how initial impulses can flower into extended exploration. Expansion often creates building effects, accumulation, and increasing engagement with subject matter. Understanding expansion reveals how poems develop temporally, with initial gestures generating extended investigation through amplification and elaboration.

Expansion extends ideas, images, or phrases across multiple lines or stanzas, developing initial concepts through elaboration. This technique creates depth and complexity by systematically unfolding meaning.
