Explanation: A comparatist is someone who specializes in comparative law, which involves comparing legal systems of different countries or regions. By doing so, comparatists can identify similarities and differences between legal systems, which can help them understand how different legal systems work and how they can be improved. For example, a comparatist may compare the legal systems of the United States and Canada to determine how they differ in terms of criminal law. This can help them identify areas where one legal system may be more effective than the other, and can lead to improvements in both legal systems.
