A jurist (from medieval Latin) is someone who researches and studies jurisprudence (theory of law). Such a person can work as an academic, legal writer or law lecturer. In the United Kingdom, Australia, New Zealand, South Africa, and in many other Commonwealth countries, the word jurist sometimes refers to a barrister, whereas in the United States of America and Canada it often refers to a judge.
There is a fundamental difference between the work of a lawyer and that of a jurist. Many legal scholars and authors have explained that a person may be both a lawyer and a jurist, but a jurist is not necessarily a lawyer, nor a lawyer necessarily a jurist. Both must possess an acquaintance with the term "law". The work of the jurist is the study, analysis and arrangement of the law -- work which can be done wholly in the seclusion of the library. The work of the lawyer is the satisfaction of the wishes of particular human beings for legal assistance -- work which requires dealing to some extent therefore with people in the office, in the court room, or in the market-place.
The term jurist has another sense, which is wider, synonymous with legal professional, i.e. anyone professionally involved with law and justice. In some other European languages, a word resembling jurist (such as Italian giurista, German Jurist, Norwegian/Danish/Swedish jurist, French juriste, Spanish and Portuguese jurista, Russian etc.) is used in this major sense.
