barrister: [16] A barrister is a lawyer who has been ‘called to the bar’ – that is, admitted to plead as an advocate in the superior courts of England and Wales. This notion derives from the ancient practice of having in the inns of court a partition separating senior members from students, which barrier the students metaphorically passed when they qualified. The ending -ister was probably added on the analogy of such words as minister and chorister. => bar[barrister etymology, barrister origin, 英语词源]
