Question

wwhich is the article used before the word author

Answer 1

an is used before the word author...


~ an author

Answer 2

Author can be anarthrous and sheep can't. Just about every profession a person can hold is ok to use without "the" and as for all the other nouns in English, I don't think there's really a rule. Off the top of my head, all the examples I can find are nouns describing something a person is. I mean that nouns like table, blizzard, whisper, and so on can't be used like this, while schoolboy, housewife, candidate, and so on all can. But I'm not sure that's a rule, it might just be that my imaginary sentence generator is slow this morning.
