" By tracing in this manner every word to its original, and not admitting, but with great caution, any of which no original can be found, we shall secure our language from being overrun with cant, from being crowded with low terms, the spawn of folly or affectation, which arise from no just principles of speech, and of which, therefore, no legitimate derivation can be shown. "
