  Most  expert  system  designers  suffer  from  knowledge   acquisition  complications.  Expert  system  shells  contain  facilities  that  can  simplify  knowledge  acquisition  to  make  domain  experts  themselves  responsible  for  k nowledge  structuring  and  encoding.  The  aim  of  this  research  is  to  develo p  an  Arabic  Expert  System  Shell  (AESS)  for  diagnosi ng diseases  based  on  natural language. The suggested AESS mainly consist s of two phases. The first phase is responsible for automatic acquiring of  human  expert  knowledge.  The  acquired  knowledge  is  a nalyzed  by  Arabic  morphological  system.  The  Arabic morphological  system  analyzes  the  given  Arabic  phrase  and  finds  t he  required  keywords  (roots).  The  suggested  system  is  provided  with  the  required domain dictionary to be used by the Arabic  morphological system. The second phase is concerne d with the design of  inference  engine  together  with  user  interface  (base d  on  natural  language)  that  uses  a  backward  chainin g  method  (end-user  interface).When  AESS  tested  by  experts  and  end  user s,  it  was  found  that  AESS  performance  in  constructing  Knowledge-Base  (KB) and diagnosing problems was very exact (the di agnostic ability of AESS is 99%.). Merging of morphological system with  knowledge  acquisition  is  very  effective  in  construc ting  the  target  KB  without  any  duplicate  or  inconsi stent  rules.  The  same  technique  could  be  used  to  build  expert  system  shel l  based  on  any  other  natural  language  (English,  Fre nch,  etc.).  The  only  difference is to build morphological system suitabl e to that language in addition to the desired domai n dictionary.
