Preconceive \Pre`con*ceive"\, v. t. [imp. & p. p.
   {Preconceived}; p. pr. & vb. n. {Preconceiving}.]
   To conceive, or form an opinion of, beforehand; to form a
   previous notion or idea of.

         In a dead plain the way seemeth the longer, because the
         eye hath preconceived it shorter than the truth.
                                                  --Bacon.
