              'account', 'across', 'act', 'action', 'activity',               'actually', 
              'add', 'address', 'administration', 'admit', 'adult',               'affect', 
              'after', 'again', 'against', 'age', 'agency',               'agent', 'ago', 
              'agree', 'agreement', 'ahead', 'air', 'all', 'allow',                'almost', 
              'alone', 'along', 'already', 'also', 'although',               'always', 
              'American', 'among', 'amount', 'analysis', 'and',               'animal', 
              'another', 'answer', 'any', 'anyone', 'anything',               'appear', 
              'apply', 'approach', 'area', 'argue',  'arm', 'around', ...
