6. The Formation of New Words.

New ideas require the formation of new words. All verbal innovations, however, have not the same justification. Horace defines the proper occasion of coining words in these lines : "If you write of things abstruse or new, Some of your own inventing may be used. So it be seldom and discreetly done." t If words must be coined, it should be "discreetly done," so that they shall conform to the established usage of the language, both as to their sources and the union of their elements. This is what Horace means in these lines :

"An undisputed power Of coining money from the fagged ore, Nor less of coining words, is still context, If with a legal public damp imprest."* Quintilian disfavors all verbal innovations. "It the new word is well received," says he, "small is the glory ; if rejec cad, it raises laughter."
