"Blighty"
A British English slang term for Britain. The word derives from a Hindustani word, vilayati, meaning "province" or "state". This term became common in India when referring to Britain and then became a popular slang term among British expatriates.
During World War I, "Dear Old Blighty" became a common term of endearment among British soldiers. A "Blighty wound", a wound not serious enough to kill but serious enough to merit a hospital stay, was enviable and, sometimes, self-inflicted by desperate soldiers.

The term came to be used again in World War I to refer to German forces and was used in propaganda to reinforce the idea that Huns, and thus Germans, were barbarians.
Trenches/trench warfare

Ypres
A Belgian municipality located in the Flemish province of West Flanders. Ypres occupied a strategic position in the war, since it stood in Germany's path to occupy Belgium and France.

English-speaking soldiers often referred to the town as Wipers through deliberate mispronunciation, as this was easier for them to pronounce. This was a common practice and was used for the names of other Belgian cities and towns.
