Sanctimonious Definition and Meaning

Sanctimonious is an adjective that means “making a hypocritical show of being morally superior to other people.”

We say that someone is sanctimonious if they pretend to be more ethical and pious than everyone else when they’re actually no better than those around them.

For example, you might say someone is a sanctimonious politician if he attacks all his competitors for committing tax fraud, while simultaneously refusing to pay his own taxes.

Origin of Sanctimonious

Originally, sanctimonious came from the Latin word sānctimōnia, which meant “sanctity” or “virtuousness.” Back then, there was no negative connotation to the word sanctimonious—it just described someone who was genuinely holy or pious.

In the 17th century, the word still had its “holy” meaning, but it also started to acquire its “holier-than-thou” meaning.

For example, Shakespeare’s play Measure for Measure includes a line about a “sanctimonious pirate that went to sea with the Ten Commandments but scraped one out of the table,” referring to a pirate who preached to others while still stealing whatever he wanted.
