Etymology Origin:
The word sanctimonious emerged in the early 17th century, combining sancti (holy) with the suffix -monious to describe someone who affects holiness rather than embodies it genuinely. Its development reflects societal skepticism toward outward displays of virtue, particularly in religious contexts. The term’s irony lies in its roots: while sanctus implies purity, -monious here underscores pretension.
