Etymology

rationalize = ration<reason> + alize<verb suffix (to make)>

  • ration (from Latin ratio, meaning "reason, calculation")
  • alize (verb-forming suffix derived from Greek -izein, meaning "to make or cause to become")

Etymology Origin:
The word rationalize originates from the Latin ratio (reason), reflecting its core meaning of applying logic or justification. The suffix -alize transforms it into a verb, emphasizing the act of making something rational. Historically, it evolved in the 18th century to describe the process of justifying actions with plausible but often superficial reasoning, later expanding to mathematical and organizational contexts.
