zealotry
UK: ˈzel.ə.tri | US: ˈzel.ə.tri
n. excessive or fanatical devotion to a cause, belief, or ideology, often to the point of intolerance or extremism.
The word "zealotry" derives from "zeal," which originates from the Greek "zēlos" (fervor, rivalry), later adopted into Latin as "zelus." The suffix "-otry" (a variant of "-try") transforms the noun into a state or practice, akin to "bigotry" or "idolatry." Historically, "zealots" were members of a Jewish sect in the 1st century CE known for militant opposition to Roman rule, embedding the term with connotations of extreme fervor. Over time, "zealotry" broadened to describe any uncompromising devotion, often with negative implications.
