All provincial or bye-phrases come under the same mark of reprobation — all such as the writer transfers to the page from his fireside or a particular coterie, or that he invents for his own sole use and convenience. I conceive that words are like money, not the worse for being common, but that it is the stamp of custom alone that gives them circulation or value. I am fastidious in this respect, and would almost as soon coin the currency of the realm as counterfeit the King's English.
—William Hazlitt, English essayist, On Familiar Style, 1821
