Let us then first suppose a portion of those speaking a language to have been separated off from the main body of its speakers, either through their forsaking for one cause or other of their native seats, or by the intrusion of a hostile people, like a wedge, between them and the others, forcibly keeping them asunder, and cutting off their communications one with the other, as the Saxons intruded between the Britons of Cornwall and of Wales. In such a case it will inevitably happen that before very long differences of speech will begin to reveal themselves between those to whom even dialectic distinctions may have been once unknown. The divergences will be of various kinds. Idioms will come up in the separated body, which, not being recognized and allowed by those who remain the arbiters of the language, will be esteemed by them, should they come under their notice, violations of its law, or at any rate departures from its purity. Again, where a colony has gone forth into new seats, and exists under new conditions, it is probable that the necessities, physical and moral, rising out of these new conditions, will give birth to words, which there will be nothing to call out among those who continue in the old haunts of the nation. Intercourse with new tribes and people will bring in new words, as, for instance, contact with the Indian tribes of North America has given to American English a certain number of words hardly or not at all allowed or known by us; or as the presence of a large Dutch population at the Cape has given to the English spoken there many words, as ‘inspan’, ‘outspan’{135}, ‘spoor’, of which our home English knows nothing. {Sidenote: _Antiquated English_} There is another cause, however, which will probably be more effectual than all these, namely, that words will in process of time be dropped by those who constitute the original stock of the nation, which will not be dropped by the offshoot; idioms which those have overlived, and have stored up in the unhonoured lumber-room of the past, will still be in use and currency among the smaller and separated section which has gone forth; and thus it will come to pass that what seems and in fact is the newer swarm, will have many older words, and very often an archaic air and old-world fashion both about the words they use, their way of pronouncing, their order and manner of combining them. Thus after the Conquest we know that our insular French gradually diverged from the French of the Continent. The Prioress in Chaucer’s _Canterbury Tales_ could speak her French “full faire and fetishly”, but it was French, as the poet slyly adds, “After the scole of Stratford atte bow, For French of Paris was to hire unknowe”.
