覚え方のコツ Memory Tip
まず mutual を確実に思い出すとよい語です。mutual understanding, mutual respect, mutual benefit のように「一方通行でなく、相手にも同じ向きのものが返る」感覚を持つと、mutuality はその関係の“性質そのもの”だと捉えやすくなります。語尾 -ity は「〜であること」を名詞化する形。単なる親しさではなく、利益・責任・配慮が双方に成り立つ対等さを表す語だと覚えると残ります。
Start from `mutual`: it appears in phrases like `mutual respect` and `mutual benefit`, where both sides give and receive. Then add `-ity`, which often means "the quality or state of." So `mutuality` is the quality of being mutual, not just a one-way connection.

mutuality の語源・成り立ち Etymology
ラテン語 mutuus「互いに交換されたもの」に由来し、-ity が「性質」を添えます。『相手から返ってくる関係』という発想が、相互性という意味の芯です。mutual や mutually も同じ語根を保っています。
Mutuality comes from mutual with the noun ending -ity. Mutual goes back to Latin mutuus, meaning "borrowed in exchange" or "reciprocal," so the root idea is of something returned between two sides. From that sense, mutuality developed to express the quality of shared exchange or reciprocity. Related words include mutual and mutually.
