The first English dictionary was published in 1604. The dictionary was actually nothing more than a list of about 3,000 difficult words, each followed by a one-word definition (定义).

The author, Robert, made no attempt to include everyday words in his dictionary. No one, he said, would ever have to look up a word in a dictionary if he already knew the meaning of the word.

In 1755, a man named Dr Johnson produced the first modern dictionary. He included in his dictionary all important words, both easy and difficult, and he had good meanings. He also gave good sentences to show how each word was actually used in speech and in writing. By the end of the 1700's, most dictionary-makers had followed Dr Johnson's example. Dictionaries were getting better and better.

The 1800's saw the greatest improvement in the quality of dictionaries. In England, scholars planned and prepared the Oxford English Dictionary, a 20-volume (册) work. One of the most interesting features is its word histories. It traces the history of each word from its earliest recorded use up to the time of the printing of the dictionary.
