One way to keep a question open is to edit it in order to render the close reasons invalid. Note that you may need to do quite a bit of work.
- If it's not a duplicate, say why the nominated question and any of the answers to that question don't cut it.
- If it's within the Help centre's listed scope, make that clear.
- It's possible you might need to provide missing research which proves the question valid. If you can do that without damaging the question, then do that.
- Perhaps you can provide a sample sentence for a word- or phrase-request, based on what the OP has already posted or commented.
- Can you pick out the detailed point which the OP is asking about with an "Is this right?" question?
- If the question is actually about the nuts and bolts of English at a level which would not really help a learner of English, demonstrate that in order that it's not migrated to ELL.
- "Off-topic" close votes have a write-in reason too, which will usually point out something specific which the question needs to address if it's to be on-topic.
- If it's unclear, provide the detail needed (if that's possible; most unclear questions need the OP to do that. But perhaps the detail has been added in comments)
- If it's too broad, limit its scope (but again, it may not be possible to judge the most important part the OP would like to keep)
- If it can be answered objectively without being pure opinion, make that clear.
None of these actions will negate close votes already cast, but they may cause people who have already voted to retract their vote, and they may prevent others from casting a close vote. And you will have improved the question.
If you can't actually do any of these to show that a question should not be closed (or rather, put on hold for the OP to clarify if possible), then it probably should be.
