Quite often, I find myself having to ask a definition question. I define a definition question as a question which main object’s name and/or definition is not known by the asker (common case) or by the community (much rarer).
These questions are challenging because, by definition, asking them properly with well-defined names is difficult (in the common case) or demonstrably impossible (in the rarer case).
This is a perfect self-fulfilling prophecy of failure: these questions tend to be misinterpreted or to be judged imprecise, therefore get downvoted and eventually put on indefinite hold.
This is unfortunate, because many such questions could lead to useful clarifications (common case) or occasional discoveries (rarer case).
Adding the definition tag could be an elegant way of addressing the problem.
Best examples from various sites:
- A popular question related to something probably deserving a better name.
- A closed question related to something that is possibly interesting.
- A solid question related to something that is imprecisely defined by the community.
- A solid question related to something that is not defined yet by the community.
