It is an English word, and it describes an occupation—a very important occupation. It is not defined in the act. Assuming it was ever controversial, perhaps some day a court could look at it. The reference, of course, is to a journalist working as a professional in a professional capacity, so I think that it is very well understood. I do not anticipate there being any problems arising. Some issues of interpretation of words arise even when you try to define them elaborately. I think that it is a very well understood term.
