The Vietnamese word "luật học" means "law studies" or "the study of law." It refers to the academic discipline that involves learning about the legal system, laws, and regulations of a country.

Luật học rất quan trọng trong xã hội.

While "luật học" specifically refers to the study of law, "luật" on its own can refer to laws in general or legal rules, and "học" can refer to any kind of study or learning.
