From the Juvenile Instructor of 1872:
What word is that in the English language
– the first two letters of which signify a man,
– the first three a woman,
– the first four a great man,
– the whole a great woman?
(If you know the answer, how about giving just a letter or two, leaving the rest to nag at other readers until the answer is posted tomorrow?)
UPDATE: The answer can be found here.
