Following the closure of my question here, I would like to know in what cases asking questions about how to read mathematical notation aloud are off-topic.
In the comments to my question, I mentioned several other questions about similar topics, but which received different treatment. For example, consider the question How can I read this mathematical sentence aloud in English?
I believe that the fact I asked a question about Russian, rather than English, may have led to this outcome. For example, if I had asked, "Does one say $(n+1)$st or $(n+1)$th?" I believe the fact that the question has a mathematical component to it would have been recognized, in that it is related to the practice of mathematics. It is hard to believe that questions specifically about the language used in mathematics can be off-topic.
EDIT: Here is another example that is no less (or more) tangentially related to mathematics than was my question. How is $e^x$ read aloud?
EDIT: Here are some more examples that could just as easily be argued to be about language.
