though I do not think that this is due to the nature of our language: the reason rather is that we have a preference for foreign goods, and therefore receive κυρταύχην with applause, whereas we can scarce defend incurvicervicus from derisive laughter. Words are proper when they bear their original meaning;

metaphorical, when they are used in a sense different from their natural meaning. Current words are safest to use: there is a spice of danger in coining new. For if they are adopted, our style wins but small glory from them; while if they are rejected, they become a subject for jest.

Still we must make the venture; for as Cicero de Nat. deorum, I. xxxiv. 95. says, use softens even these words which at first seemed harsh. On the other hand the power of onomatopoeia is denied us. Who would tolerate an attempt to imitate phrases like the much praised λίγξε βιός, Homer, Il. iv. 125. the bow twanged, and σῖζεν ὀφθαλμός 2 Od. ix. 394. the eye hissed ? We should even feel some qualms about using balare to baa, and hinntre, to whinny, if we had not the sanction of antiquity to support us.

There are special rules which must be observed both by speakers and writers. Language is based on reason, antiquity, authority and usage. Reason finds its chief support in analogy and sometimes in etymology. As for antiquity, it is commended to us by the possession of a certain majesty, I might almost say sanctity.
