Contre-rejet (anticipation)
A short element placed at a line's end, announcing the sentence unfolding in the next line — the rejet's mirror.
The contre-rejet inverts the rejet: the brief element sits at the line's end and launches a sentence that unfolds in the next line. The word suspended at the line's edge takes on an announcing relief — it opens instead of concluding, and the white space after it becomes an in-breath before the dive.
Rejet and contre-rejet are the two fine tools of line-edge work: one underlines by landing, the other by suspension. Their conscious use instantly separates crafted free verse from randomly chopped prose — the line's edges are where most of the verse-maker's craft happens.
Example
"And then / the house went dark" — "And then" hangs, loading the turn.
