sanctimonious

Sanctimonious describes individuals or behavior that exhibits a perceived moral superiority to others. Its historical roots lie in the term "sanctimonia," meaning "holiness" in Latin. Today, sanctimonious is primarily used to denote hypocritical or self-righteous behavior. The word can be applied to both language and actions that convey a sense of moral superiority. While the early 1600s saw the term sometimes used to describe genuine piety, its current usage has shifted towards describing a false or exaggerated sense of morality. Shakespeare employed both the original and modern meanings of sanctimonious in his works. The term's negative connotation highlights the discrepancy between an individual's actions and their professed moral standards.
