what are the issues, correctness, difference of meaning, of these two similar phrases?:
It could go anywhere.
It can go anywhere.
i thought to start with could is for past tense use but that's just one of its uses i think. e.g. for requests: "Could you tell me where the bank is please?" could has nothing to do with the past.
i think they're both correct but what about their meanings; how do their meanings differ? (and i guess it may come down to a personal view, not something that's written down as a formal correctness i suppose). is it a meaningless question without the phrases' context?
to start with i thought this: the could version implies "it" is not in control by you, the reader, or some other person / group of people; "it" has a mind of its own (a bird for example). and the can version is more in control by the reader/person/people. but then no, can can be equally random or known and conrolled, so i think that's rubbish now. i have no idea. that's why i'm asking.
any opinions'd be much aprpeciated.
