Of the event of this work, for which, having laboured it with so much application, I cannot but have some degree of parental fondness, it is natural to form conjectures. Those who have been persuaded to think well of my design, will require that it should fix our language, and put a stop to those alterations which time and chance have hitherto been suffered to make in it without opposition. With this consequence I will confess that I flattered myself for a while; but now begin to fear that I have indulged expectation which neither reason nor experience can justify. When we see men grow old and die at a certain time one after another, from century to century, we laugh at the elixir that promises to prolong life to a thousand years; and with equal justice may the lexicographer be derided, who being able to produce no example of a nation that has preserved their words and phrases from mutability, shall imagine that his dictionary can embalm his language, and secure it from corruption and decay, that it is in his power to change sublunary nature, and clear the world at once from folly, vanity, and affectation. With this hope, however, academies have been instituted, to guard the avenues of their languages, to retain fugitives, and repulse intruders; but their vigilance and activity have hitherto been vain; sounds are too volatile and subtile for legal restraints; to enchain syllables, and to lash the wind, are equally the undertakings of pride, unwilling to measure its desires by its strength. The French language has visibly changed under the inspection of the academy; the stile of Amelot's translation of Father Paul is observed by Le Courayer to be un peu passe; and no Italian will maintain that the diction of any modern writer is not perceptibly different from that of Boccace, Machiavel, or Caro. Total and sudden transformations of a language seldom happen; conquests and migrations are now very rare: but there are other causes of change, which, though slow in their operation, and invisible in their progress, are perhaps as much superiour to human resistance, as the revolutions of the sky, or intumescence of the tide. Commerce, however necessary, however lucrative, as it depraves the manners, corrupts the language; they that have frequent intercourse with strangers, to whom they endeavour to accommodate themselves, must in time learn a mingled dialect, like the jargon which serves the traffickers on the Mediterranean and Indian coasts. This will not always be confined to the exchange, the warehouse, or the port, but will be communicated by degrees to other ranks of the people, and be at last incorporated with the current speech.
