Definition
活动性 is a noun meaning 'mobility' or 'fluctuating nature', often used in medical or technical contexts to describe something that is not fixed — like a tumor that can move, or a currency exchange rate that changes. It combines 活动 (to move/fluctuate) with the nominalizing suffix 性 (-ness/-ity). You'll see it in phrases like 活动性肿瘤 (mobile tumor) or 活动性汇率 (fluctuating exchange rate).
