a term nearly synonymous with Cyclopaedia; but adopted in preference to it in denoting the present work, as being more definite and of better authority. According to an observation of the late learned printer Mr Bower, the preposition en makes the meaning of the word more precise: For Cyclopaedia may denote "the instruction or a circle," as Cyropedia is "the instruction of Cyrus," whereas in Encyclopaedia the preposition determines the word to be from the dative of cyclus, "instruction in a circle." And Voetius in his book De vitis fermonis, has observed, "That Cyclopaedia is used by some authors, but Encyclopaedia by the best."
