When I searched for this question, I found questions regarding whether asking for people to coin words is on-topic.
I have a little bit of a different question.
Suppose if OP is making a single word request, and is not asking for a word to be coined, but there simply is no good word for what they are asking for. Can I then answer with a newly constructed word?
I have quite a strong feeling the answer is going to be "no", but I just want to confirm it.
For example, in this question, I (somewhat jokingly) constructed the word "samsaraphobia" in a comment.
It's not absolutely new (A Google search tells me some people have used the adjective "samsaraphobic" already), but it's certainly not in any dictionary or anything like that.
Would it ever be acceptable to post such a constructed word as an answer to a single word request?
