Coining new words is a presumption to legislate in language that rarely succeeds, and before we have recourse to this dubious means it is advisable to look around in a dead and learned language to see if an expression occurs in it that is suitable to this concept; and even if the ancient use of this expression has become somewhat unsteady owing to the inattentiveness of its authors, it is better to fix on the meaning that is proper to it (even if it is doubtful whether it always had exactly this sense) than to ruin our enterprise by making ourselves unintelligible.
