The Art of Poetry: To the Pisos (44)

In the choice of his words, too, the author of the projected poem must be delicate and cautious, he must embrace one and reject another: you will express yourself eminently well, if a dexterous combination should give an air of novelty to a well-known word. If it happen to be necessary to explain some abstruse subjects by new invented terms; it will follow that you must frame words never heard of by the old-fashioned[*] Cethegi: and the license will be granted, if modestly used: and new and lately-formed words will have authority, if they descend from a Greek source, with a slight deviation. But why should the Romans grant to Plautus and Caecilius a privilege denied to Virgil and Varius? Why should I be envied, if I have it in my power to acquire a few words, when the language of Cato and Ennius has enriched our native tongue, and produced new names of things It has been, and ever will be, allowable to coin a word marked with the stamp in present request. As leaves in the woods are changed with the fleeting years; the earliest fall off first: in this manner words perish with old age, and those lately invented flourish and thrive, like men in the time of youth. We, and our works, are doomed to death: whether Neptune,[*] admitted into the continent, defends our fleet from the north winds, a kingly work; or the lake, for a long time unfertile and fit for oars, now maintains its neighboring cities and feels the heavy plow; or the river, taught to run in a more convenient channel, has changed its course which was so destructive[*] to the fruits. Mortal works must perish: much less can the honor and elegance of language be long-lived. Many words shall revive,[*] which now have fallen off; and many which are now in esteem shall fall off, if it be the will of custom, in whose power is the decision and right and standard of language.
