Read the excerpt from "Mending Wall," by Robert Frost. Something there is that doesn’t love a wall, That sends the frozen-ground-swell under it, And spills the upper boulders in the sun; And makes gaps even two can pass abreast. What is Frost describing that “doesn’t love a wall”?

Frost describes frozen ground swelling beneath the wall and pushing the stones apart. The force that makes the ground swell is ice, so the poem’s “something” that doesn’t love a wall is ice. Sunlight is mentioned as the place where the boulders spill, not as the force breaking the wall.
