Foreshadowing runover occurs when enjambment carries a line into the next with a word or phrase that subtly hints at future developments—emotional, thematic, or narrative—creating anticipatory tension; this technique merges syntactic flow with prophetic suggestion, allowing the poem to “lean forward” toward its own unfolding consequences through carefully placed linguistic cues.

A Foreshadowing runover is an enjambed line (a runover line) whose continuation onto the next line hints or subtly suggests a future event, development, or consequence in the poem's narrative or thematic arc; the break itself creates a moment of suspense before the revelation.
