The word "rationalization" stems from the Latin rationalis (reason-based), derived from ratio (calculation, reason). The suffix -ization (from Greek -izein via Latin -izare) denotes the process of making something conform to a standard. Historically, the term evolved in the 18th century to describe logical systematization, later adopted in psychology (early 20th century) to describe subconscious justification of actions. The morphemes reflect a clear progression: from ratio (logic) to rational (reasoned) to -ization (the act of applying logic).
