A metaphor is a word or group of words that is compared to another word which may not look alike physically, but which bears common similarities. A wall is not a grave nor does it look like a grave but the author's use of the metaphor shows that the Vietnam wall like a grave bore the memories of Americans who lost their lives in the Vietnam war from 1955 to 1975.

The wall bears the inscriptions of more than 50,000 names of people who have been declared dead. The poet's use of the metaphor shows that he was in a mournful mood when he visited and observed the Vietnam wall.
