ask vs. request

fadi99

I quote _Merriam-Webster's Dictionary of Synonyms_:
   Ask, request, solicit mean to seek to obtain by
   making one's wants or desires known.

   Ask implies expectation of a response, often an
   affirmative response <I am going to ask a favor of
   you> <he asked the close attention of all his
   audience> <ask the citizens for their full
   cooperation>

   Request carries a suggestion of greater courtesy
   and formality in the manner of asking and is
   preferable to ask when one feels that what one
   wants may not be granted, whether for lack of
   power or from lack of interest on the other side
   or when one wants to be exceedingly polite or
   ingratiating <request a loan> <request the
   presence of a person at a reception> <requesting
   an opportunity to present their opinions>
