Final answer:
Shelley's 'A Dirge' is named to reflect its nature as a mournful lament, similar to a funeral song, which uses the powers of nature to express sorrow over the world's wrongs.
Step-by-step explanation:
Percy Bysshe Shelley's poem "A Dirge" is titled as such because it encapsulates the essence of a funeral song or lament. The poem uses natural elements such as wild winds, storms, and the sea to express a deep sense of sorrow and mourning for the world's wrongs. By choosing the title 'dirge,' Shelley aligns his poem with the tradition of the elegy, which historically expresses grief and seeks to find consolation in the face of death; though here, the loss is more abstract, relating to the collective human condition rather than an individual.
