Many people believe that an artificial language could serve as a
neutral, easy-to-learn auxiliary language for those who engage in
international communication: tourists, businessmen, researchers,
scientists, etc. International organizations such as the United
Nations and the European Union could benefit greatly from the use
of a politically neutral auxiliary language; representatives
would be able to speak directly with one another, and the
possibility of dangerous or costly misunderstandings arising from
misleading translations would be reduced. The cost of providing
translations would also be minimized.
