Phanopoeia
Poets have also used a form of onomatopoeia to create visual images in their readers' minds. This is called phanopoeia, from the Greek word meaning “making something visible.” An example of phanopoeia is found in D. H. Lawrence's poem “Snake”:
He reached down from a fissure in the earth-wall in the gloom
And trailed his yellow-brown slackness soft-bellied down, over the edge of the stone trough
And rested his throat upon the stone bottom,
And where the water had dripped from the tap, in a small clearness
He sipped with his straight mouth, …
The rhythm, pace, and longer length of the lines create the image of a snake's slow and winding motion.
