What made Samuel Johnson’s Dictionary so good? Henry Hitchings writes in The Guardian:
One of its most important features was the use of illustrative quotations to buttress the definitions. Johnson saw that it was not enough to say what words meant; he had to show them in use. To make this possible, he scoured the literature of the previous 200 years for suitable passages. In fact, this was where he began. Rather than dreaming up a colossal wordlist and then looking for examples of each word, he began with the illustrations and worked backwards from there. So, for instance, he came across a sentence of John Locke’s in which Locke wrote of the “bugbear thoughts” which “once got into the tender minds of children, sink deep, so as not easily, if ever, to be got out again”. Drawing on this – and on five other quotations, from four other authors – Johnson could distil the essence of the word and conclude that a “bugbear” was “a frightful object; a walking spectre, imagined to be seen; generally now used for a false terror to frighten babes”.
