Sacrosanct

Look up sacrosanct in Wiktionary, the free dictionary.

Sacrosanctity was a right of tribunes in Ancient Rome not to be harmed physically. Plebeians took an oath to regard anyone who laid hands on a tribune as an outlaw liable to be killed without penalty. The term comes from the phrase sacer esto ("let him be accursed") and reflects that violation of a tribune's sacrosanctity was not only a secular offense, but a religious offense as well.^[1]
