Did you know?

Contrary to the beliefs of some, language is not sacrosanct; rather, it is subject to constant modification based on the needs, experiences, and even whims of those who use it. Take the word sacrosanct itself, which likely comes from the Latin phrase sacro sanctus meaning "made holy by a sacred rite." There's a definite semantic softening from that to the "too important and respected to be changed or criticized" meaning of sacrosanct. But holy moly, has sanctus led to a whole bunch of other English words with a truly pious flavor, from saint and sanctimony to sanctify and sanctuary. Sacrum ("a sacred rite"), source of the sacro in sacro sanctus, is no slouch either, living on in English anatomy as the name for our pelvic vertebrae—a shortening of os sacrum, which translates literally as "holy bone."
