When do I use 动作 vs 运作?

Use 动作 for concrete physical movements made by people or animals (e.g., dance, sports, gestures). Use 运作 for the abstract operation of a system, organization, or machine (e.g., how a business runs, how a computer works).

Can 运作 be used for a person's actions?

No. 运作 does not describe human bodily movements. It only refers to the functioning of non‑physical entities like systems or processes. For a person's physical actions, always use 动作.

Is 运作 a verb or a noun?

运作 can be both. As a verb, it means 'to operate' (e.g., 公司运作正常 'the company operates normally'). As a noun, it means 'operation' (e.g., 运作方式 'mode of operation'). 动作 is only a noun.

Are there any situations where 动作 and 运作 are interchangeable?

No. They belong to completely different semantic domains (physical vs. systemic). They never substitute for each other.

动作 vs 运作 (dòng zuò vs yùn zuò): physical action vs system operation

Both 动作 and 运作 share the character 作 and look visually similar, but they refer to completely different domains. 动作 (dòng zuò) is a noun for concrete physical movements or actions (e.g., gestures, dance moves). 运作 (yùn zuò) is a verb or noun for the operation or functioning of a system, organization, or process (e.g., a company, machinery, or a market). The core distinction is concrete vs. abstract: 动作 is about what a body does, 运作 is about how a system works.

动作 and 运作 both end in 作 (zuò) and share the radical 云 in their first character, making them easy to misread. However, they belong to different semantic fields. 动作 is a noun that denotes concrete physical movements or actions performed by a person, animal, or character. It is used for gestures, sports moves, dance steps, or any observable bodily action. 运作 is a verb (or occasionally a noun) that refers to the operation, functioning, or management of an abstract system — such as a business, organization, machine, or market. It emphasizes the internal processes that keep something running. Unlike 动作, 运作 does not describe bodily movements.

Quando usar cada um

动作dòng zuò

physical movement, action

Use 动作 for concrete, observable physical movements or actions. This includes gestures (手势), sports moves (动作要领), dance steps, and any motor activity performed by a living being or a character in a game/film. It is a noun and can be used with measure words like 个.

In some contexts, 动作 can also refer to a specific 'move' in martial arts or a 'motion' in animation, but it always stays in the realm of physical behavior.

运作yùn zuò

to operate, function (of a system or organization)

Use 运作 for the operation or functioning of a system, organization, institution, machine, or process. It is commonly used in formal contexts, such as business (公司运作), government (政府运作), or technical systems (系统运作). It can function as a verb (e.g., 正在运作) or a noun (e.g., 运作方式).

Unlike 动作, 运作 can take an object in the form of a system (运作公司), but most often it is used intransitively to describe how something runs.
