 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  â a wound serious enough to require recuperation away from the trenches, but not serious enough to kill or maim the victimâwas hoped for by many, and sometimes self-inflicted.
Blighty was the inevitable British soldierâs corruption of bilÄyatÄ«, meaning Britain in particular. But it only came into common use as a term for Britain at the beginning of the First World War in France about 1915.ld Blighty (historically just Blighty) is an affectionate way of referring to Britain, still common among expatriates.
