Not to be discussed (5)

Ross

I believe the answer is:

taboo

(Other definitions for taboo that I've seen before include "Beyond the pale" , "Socially prohibited" , "Inhibition based on social custom" , "Not to be mentioned" , "Anathema" .)

I've seen this clue in the Universal and the Wall Street Journal.
