RE: What is an archery professional?
If refering to Professional as a noun- to a Name of someone as........
Professional;a : participating for gain or livelihood in an activity or field of endeavor often engaged in by amateurs <a professional golfer> b : having a particular profession as a permanent career <a professional soldier> c : engaged in by persons receiving financial return <professional football>
I think that anyone that totally depends on monies earned is a professional as they have chosen a profession It however does not make them a good one. I have seen on this board through-out the years things such as " Professional outdoor writer" and such. If that is how you earn your income then I guess you would be, even it you only get $10 a year but have no other income.
Now if used as and adjective... one would be describing someones actions,
I think if they do not earned a living at something, if they acted in a Professional manner, then they could be acting as a professional, but really would not be.
