Enjambment
The continuation of a sentence or phrase past the end of a line of verse without a pause.
Enjambment lets a thought spill over the line break so the reader is pulled onward to complete it. Writers use it to create momentum, surprise, or a tension between the eye’s pause at the line’s edge and the sentence’s push forward. It is the opposite of an end-stopped line that closes on its own punctuation.
Example
Williams breaks phrases mid-thought so each fragment hangs briefly, forcing the reader to slow down and see the plain images anew.
