What are the are the figures of speech in the poem "Meeting at Night" by Robert Browning?

I can help point out a few to get you
started:

1.  Personification.  This is where you give
inanimate objects human-like characteristics.  It helps things to have more life and
depth to them.  In this poem, Browning refers to "the startled little waves."  Waves
cannot be startled; that is tying a human reaction to an object in nature, and it makes
the waves seem alive and active.  He also says that the waves were roused "from their
sleep," again tying the ocean to traits of humans.

2. 
Onomatopoeia.  This is when the words sound like the thing that they are describing, for
example, "hiss" to describe the sound a cat makes when angry.  In the poem, the flame of
the match "spurts," the sand is "slushy," their hearts are "beating," and the narrator
"taps" and "scratches" at the windowpane.  These words help the reader to feel like they
are right there, hearing the noises.

3.  Alliteration. 
This is when two or more words in a sentence begin with the same consonant sounds.  In
this poem, we have the "pushing prow," and the "slushy sand," the moon is "large and
low," and there is a "sharp scratch" at the window.  The use of alliteration helps the
poem to flow and have cadence.

I hope that those help to
get you started; good luck!
