Fluid, liquid, watery, and runny all mean flowing like a liquid. Fluid often describes smooth, graceful style or movement, not an actual liquid. Liquid is the plain word for the flowing state. Watery means weakened by water. Runny is informal, for a runny nose.

这四个词都能形容“像液体一样流动”的状态，但语气和典型搭配不同：fluid 多用于比喻动作、风格或局势的流畅、易变；liquid 是最基础、中性的字面用词，指物质本身呈液态；watery 因水分过多而显得稀薄，常带贬义；runny 是口语化用词，多搭配鼻涕、鸡蛋、颜料等具体名词。这里不比较 liquid 作名词表示“液体”本身的用法，也不比较 fluid 表示“资金流动性”等引申义。
