rationale = ration<reason> + ale<noun suffix>
- ration (from Latin ratio, meaning "reason, calculation")
- ale (a noun-forming suffix, often derived from Latin -alis or -ale, indicating relation or pertaining to)
Etymology Origin:
The word "rationale" originates from the Latin rationalis, meaning "of or pertaining to reason." It evolved through Late Latin rationale (a neuter noun form) into Medieval Latin as rationalis (justification). The term entered English in the 17th century, retaining its core meaning of a logical foundation or systematic explanation. The morpheme "ration" preserves the original Latin root for "reason," while the suffix "-ale" nominalizes the concept, turning it into a tangible explanation or justification.
