   Syn: To conjecture; suppose; surmise; suspect; divine; think;
        imagine; fancy.

   Usage: To Guess, Think, Reckon. Guess denotes, to
          attempt to hit upon at random; as, to guess at a thing
          when blindfolded; to conjecture or form an opinion on
          hidden or very slight grounds: as, to guess a riddle;
          to guess out the meaning of an obscure passage. The
          use of the word guess for think or believe, although
          abundantly sanctioned by good English authors, is now
          regarded as antiquated and objectionable by
          discriminating writers. It may properly be branded as
          a colloguialism and vulgarism when used respecting a
          purpose or a thing about which there is no
          uncertainty; as, I guess I 'll go to bed.
          [1913 Webster]
