 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.
The blight fungus is carried from tree to tree by small animals and insects, who pick up and thansport the infected spores from tree cankers on their feet, fur, and feathers. The disease is also spread from tree to tree by weather elements such as wind and rain.
