A lawyer or jurisconsult (from medieval Latin) is a legal expert or someone who researches case law.  Such a person may be an academic (jurist), a legal writer, a lecturer in law and a legal practitioner (lawyer), depending on the legislation of the respective jurisdiction. Professionally, the word lawyer in the United Kingdom, Australia, New Zealand, South Africa and many other Commonwealth countries sometimes refers to a lawyer and a lawyer, while in the United States of America it often refers to a judge.  The term lawyer has a different meaning, which is broader, synonymous with lawyer, that is, any person who is professionally involved in law and justice.  In other European languages, a word similar to jurist is used in this main sense (e.g. Italian Giurista, German lawyer, Norwegian/Danish/Swedish/Dutch lawyer, French lawyer, Spanish/Catalan/Portuguese jurista, Galician xurista, Russian ?????, etc.). There is a fundamental difference between the work of a lawyer and that of a lawyer.  Many jurists and authors have stated that a person can be both a lawyer and a lawyer, but a lawyer is not necessarily a lawyer, nor necessarily a lawyer. Both must be familiar with the term “law.” The lawyer`s job is the study, analysis and arrangement of the law – work that can be done completely in the isolation of the library. The lawyer`s job is the satisfaction of some people`s desires for legal assistance – a job that, to some extent, requires dealing with people in the office, in the courtroom or in the market. Thus, a lawyer, someone who studies, analyzes and comments on the law, opposes a lawyer, someone who applies the law on behalf of clients and thinks about it in practical terms.
