Answers that are not definite and suggest a variety of options are not acceptable answers.
Input: Question: I've heard people say "be king" (as in "I can't wait to be king") in movies and TV. Why don't they say "be a king"? Which is correct? 
Answer: Oddly enough, I think "to be king", "to be a king" and "to be the king" are all different. If you say "to be a king", like recognizer says, it would imply one of any number of kings, whereas if you say "to be the king", it would imply one specific king of one specific kingdom. On the other hand, if you say "to be king", it's like you're saying "to have the attributes and/or capabilities that come with being (a/the) king", whichever those are. In other words, one can be "a king" or "the king" and still not "be king", if such states do not apportion to their monarchs the features of "being king". And, one can "be king" even without being "a king" or "the king", if such features are made available in some other way, unlikely as that may be. Note that I'm not talking about metaphorical meanings of "king", here (like, say, the "king of rock'n'roll"), but of literal meanings, such as monarch or ruler.
