We are not to suppose that in actual fact the transitions from one signification to another are so strongly and distinctly marked, as I have found it convenient to mark them here. Indeed it is hard to imagine anything more gradual, more subtle and imperceptible, than the process of change. The manner in which the new meaning first insinuates itself into the old, and then drives out the old, can only be compared to the process of petrifaction, as rightly understood--the water not gradually turning what is put into it to stone, as we generally take the operation to be; but successively displacing each several particle of that which is brought within its power, and depositing a stony particle, in its stead, till, in the end, while all appears to continue the same, all has in fact been thoroughly changed. It is precisely thus, by such slow, gradual, and subtle advances that the new meaning filters through and pervades the word, little by little displacing entirely that which it before possessed.
No word would illustrate this process better than that old example, familiar probably to us all, of ‘villain’. The ‘villain’ is, first, the serf or peasant, ‘villanus’, because attached to the ‘villa’ or farm. He is, secondly, the peasant who, it is further taken for granted, will be churlish, selfish, dishonest, and generally of evil moral conditions, these having come to be assumed as always belonging to him, and to be permanently associated with his name, by those higher classes of society who in the main commanded the springs of language. At the third step, nothing of the meaning which the etymology suggests, nothing of ‘villa’, survives any longer; the peasant is wholly dismissed, and the evil moral conditions of him who is called by this name alone remain; so that the name would now in this its final stage be applied as freely to peer, if he deserved it, as to peasant. ‘Boor’ has had exactly the same history; being first the cultivator of the soil; then secondly, the cultivator of the soil who, it is assumed, will be coarse, rude, and unmannerly; and then thirdly, any one who is coarse, rude, and unmannerly{ 221}. So too ‘pagan’; which is first villager, then heathen villager, and lastly heathen. You may trace the same progress in ‘churl’, ‘clown’, ‘antic’, and in numerous other words. The intrusive meaning might be likened in all these cases to the egg which the cuckoo lays in the sparrow’s nest; the young cuckoo first sharing the nest with its rightful occupants, but not resting till it has dislodged and ousted them altogether.
