Sacrosanct is an adjective that means regarded as too important or valuable to be interfered with.

Our word of the day is derived from the Latin phrase sacro sanctus (SOCK row SONG toos) which means ‘hallowed by a sacred rite.’ Sacrosanct is often thought of as a synonym of sacred, but it is more likely to be used in reference to things that have nothing to do with religion, for example: Our team’s playbook was sacrosanct as far as our coach was concerned. He’d lose his mind if he found one laying around on the locker room floor or, worse yet, in the trash can.
