Concept:A simile is a figure of speech that compares two different things using the words "like" or "as".
Explanation:The line "Light as wind on water laid" describes light by comparing it to wind moving over water.
The word "as" directly joins these two images.
The phrase "as wind on water laid" suggests the same gentle and effortless quality found in both light and wind.
Because the comparison is made explicit with "as", the device is a simile.
It is not a rhyme, since no sound repetition is involved.
It is not onomatopoeia, because no word imitates a natural sound.
It is not a pun, because no double meaning is intended.
Therefore, the line makes a simple imaginative comparison.
