There has been renewed interest in my D&D 5e question Can a spell be prepared once and cast multiple times?, which has been marked as a potential duplicate of How does wizard & cleric spell preparation and casting work?.
They do have similar names, but I don't feel that it is a duplicate because the other question is extremely broad, talking about all aspects of spell preparation. In fact, the accepted answer only has two sentences a third of the way into the response that refer to my question about if a spell can be prepared once and cast multiple times. (Or to use another metric, 52 words in a 922 word response).
If someone came to the site wanting to know the answer to the same question as I asked, that's a lot of text they'd have to wade through to get to that answer.
There was a similar situation in Non-duplicate question with answer in another question where a question was marked as duplicate and the OP thought that the duplicate question was too broad, and others agreed. I think that situation was a bit more cut and dry than this one though.
Is a question really a duplicate if the other question is so broad that the answer is such a small fraction of it?
