The article explores the difficult spelling of the English language, particularly the use of the letters GH. It explains how the Norman Conquest of England in 1060 led to changes in the language and spelling, and how the GH sound was an attempt by the Normans to write a sound they did not have in their own language. The article also notes that the GH spelling is no longer used in modern English, but remains in some new words and serves as a reminder of the language's history.
