Which pair of lines in this poem contains enjambment? it is a beauteous evening, calm and free by william wordsworth it is a beauteous evening, calm and free, the holy time is quiet as a nun breathless with adoration; the broad sun is sinking down in its tranquility; the gentleness of heaven broods o'er the sea; listen! the mighty being is awake, and doth with his eternal motion make a sound like thunder—everlastingly. dear child! dear girl! that walkest with me here, if thou appear untouched by solemn thought, thy nature is not therefore less divine: thou liest in abraham's bosom all the year; and worshipp'st at the temple's inner shrine, god being with thee when we know it not.

Enjambment will occur in the middle of sentence where a sentence is split up between two lines without any sort of punctuation.  The sentence is sort of “jammed” to fit into two lines.  Thus, when looking for enjambment, we’ll be looking for a complete sentence that takes up more than one line and is missing punctuation at the end of the first line to where it (without pause) continues into the next line.  That said, there are actually three instances of enjambment within the poem:

In these two lines, the idea of a breathless nun is enjambed:

The holy time is quiet as a Nun  

Breathless with adoration; the broad sun

In these two lines, the notion of the sinking sun is enjambed:  

Breathless with adoration; the broad sun  

Is sinking down in its tranquility;

In these two lines, the idea of motion making a sound is enjambed:  

And doth with his eternal motion make  

A sound like thunder—everlastingly.

Breathless with adoration; the broad sun

Is sinking down in its tranquility
