覚え方のコツ Memory Tip
reasoning は reason「筋道立てて考える」に -ing を加えた名詞で、結論そのものより「そこへ至る考え方・根拠」を指します。explain your reasoning「推論過程を説明する」、logical reasoning「論理的推論」が定番。reason が個々の「理由」にもなるのに対し、reasoning は考えの流れ全体を表します。
Take the verb reason, “think in a logical way,” and add -ing to name the process: reasoning. Picture a chain leading from evidence through several steps to a conclusion. This helps distinguish reasoning from a reason, which may be one particular cause or explanation. Useful combinations include logical reasoning, reasoning ability, line of reasoning, and explain your reasoning. When a teacher asks for your reasoning, the answer should show how you reached the result, not merely state the final answer.

reasoning の語源・成り立ち Etymology
reasoningはreason＋-ing。reasonは古フランス語raison、さらにラテン語ratio「計算・判断」にさかのぼり、数え合わせる感覚が「筋道立てて考える」意味へ広がった。関連語はreason、rational。
Reasoning is formed from reason and the noun-forming use of -ing. Reason entered English through Old French raison from Latin ratio, which could mean calculation, account, judgment, or method. Ratio itself is related to the Latin verb reri, “to reckon” or “think.” The historical movement from reckoning or accounting to orderly thought helps explain the modern sense of a logical process leading toward a conclusion.
