Every increase of knowledge, whether real or fancied, will produce new words, or combination of words. When the mind is unchained from necessity, it will range after convenience; when it is left at large in the fields of speculation, it will shift opinions; as any custom is disused, the words that expressed it must perish with it; as any opinion grows popular, it will innovate speech in the same proportion as it alters practice.
—Samuel Johnson, British lexicographer and literary critic, Preface to A Dictionary of the English Language, 1755
