Etymology
The word 'reasonable' originates from the Latin 'ratiōnābilis', meaning "endowed with reason." It entered English via Old French 'raisonable'. The core Latin root 'ratiō' initially referred to a "reckoning, calculation, or account," which evolved to signify the faculty of logical thinking and justification. The suffix '-able' attaches to this root to create an adjective describing something that possesses or is characterized by reason. Thus, the literal sense of "capable of reason" broadened to encompass the modern meanings of being sensible, fair, and moderate, as these qualities are seen as products of sound reasoning.
