This is a spin-off suggestion from Add a 'too basic' close reason. I put forth that we already do have a 'too basic' reason, General Reference, but the wording should be improved. Here is what I suggest:
It appears that your question might be answerable through commonly-available references. Please provide more detail about the research you've done, or consider if the question might be better suited to our English Language Learners sister site.
Updated from comments:
This addresses the three buckets of questions that I believe commonly fall into the GR dumping ground. Ones that:
- Definitely could be answered using commonly-available references.
- Show no evidence of research, so it seems like they might be answered by common references. If the OP adds evidence of what research they did and why they're still confused, it might actually be a good question.
- Are too basic / obvious to native speakers, and don't fall within this site's charter. They might be good questions for ELL, but maybe not. There have been various discussions (like this one) that hint that an auto-migration path to ELL may never exist, even after it graduates.
I would not oppose having three separate close reasons, but I think we're limited in how many we could have.
