April is the cruellest month, breeding Lilacs out of the dead land, mixing Memory and desire, stirring Dull roots with spring rain.
The poem opens with a voice that finds renewal painful. Spring forces dormant memories and desires back to life. The speaker prefers the anesthetic of winter, which "kept us warm" in forgetful snow. This paradox — life as cruelty — sets the emotional key for the entire poem.
The most famous opening in modernist poetry — inverting the traditional celebration of spring into a statement of existential dread.
