I recently asked a question about GRE wording conventions and was immediately told that I was off-topic. I promptly removed the question to avoid clutter, and decided instead to ask here:
Are questions about ETS’ GRE wording conventions on-topic or off-topic on the Academia Stack Exchange? If off-topic, is there a known appropriate venue?
Note that this is not about GRE vocabulary, but about the anchor words that ETS uses to describe the desiderata in their GRE questions.
EDIT: Per current discussion under @wrzlprmft's answer, I'm tilting this question towards the USA audience (those more familiar with the ETS and the GRE). I've removed the examples as they've apparently resulted in more confusion than clarification of what makes a convention a convention versus a standard.
