Etymology Origin:
The word "reason" traces back to Latin ratio, meaning "calculation" or "logical faculty." It entered English via Old French raison, evolving from a concrete sense of "mathematical reckoning" to the abstract idea of "logical thought" or "justification." The suffix -on (from Latin -ionem) solidified its role as a noun representing a mental process. This shift reflects humanity's growing emphasis on structured thought over mere instinct.
