A more thorough explanation:

An academic lawyer is a law professor who also practices law outside of academia. This means that they teach law courses at a university or law school, but they also work as a lawyer in the real world.

• Professor Smith teaches constitutional law at a university, but also takes on cases as a civil rights lawyer.
• Professor Johnson is a law professor who specializes in environmental law, but also works as a consultant for companies on environmental regulations.

These examples illustrate how academic lawyers balance their roles as educators and practitioners. They use their knowledge and experience to teach students about the law, while also applying that knowledge in their own legal work.
