阴性

• ピンイン: yīn xìng
• 漢字の分解: 阴 = 阜 + 侌 (mound + obscured sun — the Yin side, negative); 性 = 忄+ 生 (heart + birth — inherent nature, quality)

意味

（検査結果の）陰性；（中医学などの）陰（yin）の性質

In modern medical usage, 阴性 almost always means a negative test result (检测阴性 — test negative). In traditional Chinese medicine, it refers to the Yin quality: cold, dark, passive, receptive. In linguistics (gender systems), it means feminine gender. Context determines which sense is meant. The medical sense is by far the most common in everyday advanced Chinese.

例文
