 Blighty  is a British English slang term for Britain or often specifically England. It was first used during the Boer War, though it was not until World War I that the word spread widely.he term was particularly used by World War I poets such as Wilfred Owen and Siegfried Sassoon. During that war, a  Blighty wound  — a wound serious enough to require recuperation away from the trenches, but not serious enough to kill or maim the victim—was hoped for by many, and sometimes self-inflicted.
