To analyze T.S. Eliot's language in describing the city in "The Love Song of J. Alfred Prufrock" and its connection to modernist themes, it is important first to grasp what modernism entails. Broadly, modernist themes often revolve around ideas of alienation, change, materialism, and subjective truths.
With this in mind, Eliot's depiction of the city embodies these themes by questioning life’s meaning and fostering feelings of isolation, despair, and loss typical of modernist work.
An example of paralysis appears early in the poem with the lines:
“Let us go then, you and I,
When the evening is spread out against the sky
Like a patient etherized upon a table”
Here, London’s night sky is compared to a sedated patient, conveying passivity and numbness that shadow Prufrock throughout the piece.
