Mnemonic
Dig into the earth and you hit another layer of earth beneath it. When rain soaks through both layers, they blend into thick, sticky mud that swallows your boots whole. Double earth means double the mud—nowhere to step without sinking!
Additional thoughts
Two earth radicals stacked together suggest earth mixed with more earth, breaking down into wet, gooey mud. Picture two dirt layers collapsing into slop after a storm.Quick recall
Two layers of earth on earth get soaked and become deep, boot-swallowing mud.
