Perhaps you should try some spelling variations:
competitivenes » competitiveness, scompetitiveness, competitiviness
competitivenest » competitivenesst, scompetitivenesst, competitivinesst, competitiveness
ccompetitiveness » ccompetitivenesss, cscompetitivenesss, ccompetitivinesss, competitiveness, scompetitiveness, competitiviness
competiveness » competitiveness
completeness » complements, competences

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((competitivenes OR competitivenest) or ccompetitiveness) or (competiveness or completeness))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((competitivenes OR competitivenest) OR ccompetitiveness) OR (competiveness OR completeness))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((competitivenes OR competitivenest) or ccompetitiveness) or (competiveness or completeness))*".
