![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
never
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for never that I've seen before include "At no time in the past or future" , "Not in a million years!" , "Strong negative" , "Emphatic negative" , "Surely not" .)
