essential nature ★☆☆☆☆
(sex / essential nature) + (quality) = 性質 (essential nature)

natural quality. In contrast to 性格(せいかく), 性質 applies to rocks and things as well as people and animals. Also it refers to the inner nature of people, rather than their social selves. So if you wanted to say that someone was very outgoing and loved sports and bars, you wouldn't use 性質. But if you wanted to say that someone was very stoic or honest, you would.
