Enjambment  In poetry, when one line ends without a pause and continues into the next line for its meaning. This is also called a run-on line. The transition between the first two lines of Wordsworth's poem "My Heart Leaps Up" demonstrates enjambment:

My heart leaps up when I behold
A rainbow in the sky
