Boundary enjambment is an enjambment that pushes a poetic line beyond normal spatial or visual boundaries on the page, such as spilling into margins or over design elements. It emphasizes overflow of thought or emotion, creating visual tension. While unconventional, it can symbolize breaking constraints or expanding meaning beyond the poem’s structural frame.

Boundary enjambment occurs when a line of verse runs beyond an expected visual or spatial boundary, such as a margin, column, page edge, stanza division, or other typographic limit. It can make syntax feel interrupted, excessive, unstable, or expansive. Unlike ordinary enjambment, its visual layout is central to the effect. Read both the line break and the continuing phrase aloud; in drafting, test whether the unusual placement clarifies rather than merely decorates meaning.
