Being intrigued by this question (What is the name of this rat) I took the trouble to google it and post the answer as a comment. But it got me to thinking. It seems to me...
“Supreme court” vs. “highest court” is legal terminolgy.
Relationship between professor and student is academia.
Describe someone who feels little or no emotion? is medical.
Word to describe a mathematical variable that repeats is mathematics.
What are the proper terms for these star shapes is geometry.
I don't really understand the logic of allowing some "What's this called?" questions, but not others. I'd probably have voted to close the "rat" question myself if it had already been answered, on the grounds that once "the correct answer" has been posted there's no need for any more.
Short of saying some/all of the above counterexamples should also have been closed immediately, what exactly is the thinking here?
