The word "reformer" traces back to Latin reformare ("to shape again"), combining re- (expressing repetition) and formare ("to shape"). The suffix -er denotes an agent, creating a noun meaning "one who reshapes or improves." Historically, it gained prominence during the Protestant Reformation (16th century), where reformers like Martin Luther sought to "reshape" religious practices. The term later broadened to secular contexts, emphasizing systematic improvement.
