Who is lawyer?

A lawyer is "a person learned in the law; as an attorney, counsel or solicitor; a person licensed to practice law." Law is the system of rules of conduct established by the sovereign government of a society to correct wrongs, maintain stability, and deliver justice. Working as a lawyer involves the practical application of abstract legal theories and knowledge to solve specific individualized problems, or to advance the interests of those who retain (i.e., hire) lawyers to perform legal services.

The role of the lawyer varies significantly across legal jurisdictions, and so it can be treated here in only the most general terms.
