The plan which I have laid down for myself, and to which I shall adhere, in this lecture and in those which will succeed it, is as follows. In this my first lecture I will ask you to consider the language as now it is, to decompose with me some specimens of it, to prove by these means, of what elements it is compact, and what functions in it these elements or component parts severally fulfil; nor shall I leave this subject without asking you to admire the happy marriage in our tongue of the languages of the north and south, an advantage which it alone among all the languages of Europe enjoys. Having thus presented to ourselves the body which we wish to submit to scrutiny, and having become acquainted, however slightly, with its composition, I shall invite you to go back with me, and trace some of the leading changes to which in time past it has been submitted, and through which it has arrived at what it now is; and these changes I shall contemplate under four aspects, dedicating a lecture to each;--changes which have resulted from the birth of new, or the reception of foreign, words;--changes consequent on the rejection or extinction of words or powers once possessed by the language;--changes through the altered meaning of words;--and lastly, as not unworthy of our attention, but often growing out of very deep roots, changes in the orthography of words. {Sidenote: _Alterations unobserved_} I shall everywhere seek to bring the subject down to our present time, and not merely call your attention to the changes which have been, but to those also which are now being, effected. I shall not account the fact that some are going on, so to speak, before our own eyes, a sufficient ground to excuse me from noticing them, but rather an additional reason for doing this. For indeed changes which are actually proceeding in our own time, and which we are ourselves helping to bring about, are the very ones which we are most likely to fail in observing. There is so much to hide the nature of them, and indeed their very existence, that, except it may be by a very few, they will often pass wholly unobserved. Loud and sudden revolutions attract and compel notice; but silent and gradual, although with issues far vaster in store, run their course, and it is only when their cycle is completed or nearly so, that men perceive what mighty transforming forces have been at work unnoticed in the very midst of themselves.
