Profession

A profession is a vocation founded upon specialised educational training, the purpose of which is to supply disinterested objective counsel and service to others, for a direct and definite compensation, wholly apart from expectation of other business gain. The term is a truncation of the term "liberal profession", which is, in turn, an anglicisation of the French term "profession libérale". Originally borrowed by English users in the 19th century, it has been re-borrowed by international users from the late 20th, though the (upper-middle) class overtones of the term do not seem to survive retranslation: “liberal professions” are, according to the Directive on Recognition of Professional Qualifications (2005/36/EC) “those practised on the basis of relevant professional qualifications in a personal, responsible and professionally independent capacity by those providing intellectual and conceptual services in the interest of the client and the public”.
