Invention of Dictionary.
The word dictionary has come from the Latin word dictionarium. A school master named Robert Cowdrey , prepared the first English dictionary in 1604 A.D. In 1721, Nathan Balley published a dictionary with about 60,000 words which was the first real dictionary. The Oxford English dictionary was published in 12 volumes in 1933. It was a work of John Walker . In 1989, it came to have 20 volumes.
