It's Merriam-Webster's Word of the Day for July 24th.
Today's word is sanctimonious, spelled S-A-N-C-T-I-M-O-N-I-O-U-S.
Sanctimonious is an adjective.
Someone described as sanctimonious behaves as though they are morally superior to others.
Language or behavior that suggests the same kind of moral superiority can also be described as sanctimonious.
Here's the word used in a sentence from Variety.
Smart and sincere but never sanctimonious,
the awareness-raising drama doubles as a public service message of sorts.
There's nothing sacred about the word sanctimonious, at least not anymore.
But in the early 1600s,
the English adjective was still sometimes used to describe someone truly holy or pious,
a sense at an important remove from today's use,
describing someone who acts or behaves as though they are morally superior to others.
The now obsolete pious sense recalls the meaning of the words Latin parent sanctimonia,
meaning holiness or sanctity.
Shakespeare used both the holy and holier-than-thou senses of sanctimonious in his work,
referring in the tempest to the sanctimonious, that is the holy,
ceremonies of marriage,
and in measure for measure to the sanctimonious pirate that went to sea with the ten commandments but scraped one out of the table.
Apparently the pirate found the restriction on stealing inconvenient.
