The Chinese word **投资者** (tóuzīzhě), meaning "investor," is formed through a logical and common Mandarin compound word structure: it combines the verb-object phrase **投资** (tóuzī), meaning "to invest capital" (where 投 means "to throw/put in" and 资 means "capital/resources"), with the nominalizing suffix **者** (zhě), which denotes "a person who does the action." Therefore, the word is constructed as **"从事投资活动的人"** (a person who engages in investment activity), creating a precise and agentive noun directly from its verbal core.
