motion

Compared meaning: the act of moving, a change of position (noun).

比较义项：移动、挪动（的动作）（名词）。

• movement

  The general, often continuous act or manner of moving, common for describing body movements, dance, or exercise; more everyday in tone than motion, and not tied to one specific instance.

  泛指移动的动作或方式，常用于描述身体动作、舞蹈或锻炼中持续或反复的动作；语气比motion更日常，不特指某一次具体的动作。

  Her movements grew slower as she grew more tired during the run.

  在跑步过程中，随着她越来越疲惫，她的动作变得越来越缓慢。

• move

  A single, concrete instance of changing place or position, usually countable (a move, the move); more specific and discrete than the general, often uncountable movement or motion.

  指改变位置的一次具体、单一的动作，通常可数（a move，the move）；比泛指、常不可数的movement或motion更加具体、单一。

  Their move to the new city took nearly three months to complete.

  他们搬到新城市，前后花了将近三个月才完成。

• motion 本词

  The general act of moving, but more formal or technical than movement; used in fixed expressions like motion detector, in motion, or slow motion, especially in science or machinery contexts.

  同样泛指移动的动作，但比movement更正式、更具技术性，常用于固定搭配，如motion detector（运动探测器）、in motion（运动中）、slow motion（慢动作），多见于科学或机械语境。

  The camera captured the falling leaves in slow motion.

  摄像机以慢动作捕捉到了飘落的树叶。

Movement, move, and motion relate to moving. Move is one specific, countable change of position, like a house move. Movement and motion are more general words for the act of moving. Their other senses — social movement, meeting motion, strategic move — are not compared.

movement、motion、move在此义项上都与“移动”有关，但move通常指一次具体、单一的位置变化（如搬家、搬迁），可数且更具体；movement和motion则泛指移动的动作或过程，其中motion更正式、偏技术性（常见于motion detector、in motion等固定搭配），movement更日常，多用于描述身体动作。这里不比较movement表示“（社会）运动”的意义、motion表示“（会议上的）提议、动议”的意义、以及move表示“（策略性的）一步棋、招数”的意义。

Compared meaning: a hand or body movement with meaning (noun).

比较义项：手势（名词）。

• motion 本词

  More formal and less common in this sense; emphasizes the physical movement itself rather than its communicative meaning, often in written or descriptive contexts.

  在这个意义上更正式，也不如 gesture 常用；强调动作本身的移动过程，而不是它所传达的含义，常见于书面或描述性语境。

  The camera captured the motion of the runners crossing the line.

  摄像机捕捉到了跑步者们冲过终点线时的动作。

• gesture

  The everyday word for a hand or body movement that conveys meaning; used constantly in speech, especially for small, deliberate signals like waving or pointing.

  是日常最常用的词，指用手或身体传达意思的动作；在口语中极为常见，尤指挥手、指点等细小而刻意的信号。

  She made a small gesture with her hand to say hello.

  她用手做了一个小小的手势来打招呼。

Motion and gesture both can mean a hand or body movement with meaning. Gesture is the everyday, common word, used constantly for signals like waving or pointing. Motion is more formal here, focusing on the physical movement itself. Motion's general 'movement' meaning is not compared.

两者都可指用手或身体做出的、传达含义的动作，但 gesture 是日常最直接、最常用的说法，而 motion 在这个意义上更正式、也更强调“动作的移动过程”本身。这里不比较 motion 的其他常见义项，例如“运动、移动”（物理意义上的运动）。

Compared meaning: movement, physical motion (noun).

比较义项：运动，移动（名词）。

• movement

  Refers to a specific, often countable instance or pattern of moving, such as a gesture or a step in dance or exercise; feels concrete and everyday.

  指具体的、通常可数的一次动作或一套动作，例如一个手势或舞蹈、锻炼中的一个动作；给人的感觉具体而日常。

  The teacher praised her precise movements during the dance routine.

  老师称赞了她在这套舞蹈动作中精准的动作。

• motion 本词

  An uncountable, more abstract or technical word for the state or process of moving, typical of science, mechanics, or fixed phrases like slow motion.

  是不可数、更抽象或更专业的说法，指移动的状态或过程，常见于科学、机械语境或固定搭配，如slow motion（慢动作）。

  The replay showed the goal in slow motion, frame by frame.

  回放以慢动作、逐帧的方式展示了这个进球。

Movement and motion both mean movement. Movement refers to a specific, countable action, like a dance movement, and sounds more everyday. Motion is an uncountable, technical word, common in fixed phrases like 'slow motion'. Their other meanings, 'social movement' and 'meeting motion', are not compared.

这两个词在“运动、移动”这一义项上意思相近，但movement通常指具体、可数的一次动作或一系列动作，语气更自然、口语化；motion是不可数的抽象说法，常用于科学、机械语境或固定搭配（如slow motion、in motion）。这里不比较movement的“（政治或社会）运动”义项，也不比较motion的“（会议上的）提案、动议”义项。
