Read the excerpt from Samuel Johnson’s preface to A Dictionary of the English Language. But to COLLECT the WORDS of our language was a task of greater difficulty: the deficiency of dictionaries was immediately apparent; and when they were exhausted, what was yet wanting must be sought by fortuitous and unguided excursions into books, and gleaned as industry should find, or chance should offer it, in the boundless chaos of a living speech. My search, however, has been either skilful or lucky; for I have much augmented the vocabulary.

The excerpt claims that Johnson’s work is significant because he

changed the format of dictionaries.
searched literature and found more words.
applied rules to make language less chaotic.
selected only the most difficult words to define
