Animation Vocabulary in English

20 essential animation words with definitions and example sentences — frames, rigging, and rendering for B2–C1 ESL learners.

Pedagogically reviewed by LexFizz Team

Animation vocabulary describes the creative and technical process of bringing drawings, models, or digital characters to life on screen. Words such as keyframe, rigging, and rendering carry precise meanings used across film, television, and video game studios. You can check the full entry for any of these terms in the Cambridge Dictionary.

This page covers 20 key animation words used in production studios, tutorials, and reviews of animated films and games. These terms appear whenever animators discuss their workflow, tools, or techniques.

Unlike our broader Film and Cinema vocabulary and Video Games vocabulary pages, this list focuses specifically on the techniques used to create movement and character performance frame by frame. Mastering this vocabulary will help you follow behind-the-scenes documentaries, read production credits, and discuss animation with confidence.

animatora person who creates the illusion of movement in drawings, models, or digital charactersThe animator spent two days perfecting a single three-second walk cycle.A2
framea single still image that, shown quickly in sequence with others, creates the illusion of movementTraditional animation is often drawn at twenty-four frames per second.A2
keyframea frame that defines the starting or ending point of a smooth transition or movementThe lead animator drew the keyframes first, leaving the in-between poses for later.B1

lip syncmatching a character's mouth movements accurately to recorded spoken dialoguePoor lip sync can make even great voice acting feel unconvincing on screen.B1
easingthe gradual speeding up or slowing down of a movement, rather than constant speed, to look naturalAdding easing to the bouncing ball made its motion feel far more realistic.B2
walk cyclea short, repeating sequence of frames showing a character walking, designed to loop seamlesslyAnimators often perfect a basic walk cycle before tackling more complex character actions.B1
compositingcombining multiple visual elements, such as characters, backgrounds, and effects, into a single final imageCompositing brought together the hand-drawn character and the digitally painted background.C1

Frequently Asked Questions

What is animation?

Animation is the technique of creating the illusion of movement by displaying a rapid sequence of still frames, whether hand-drawn, model-based, or created with 3D software. It is used in films, television, video games, and advertising.

What is the difference between a keyframe and an in-between?

A keyframe marks an important pose or moment, such as the start or end of a movement. An in-between is a frame created to smoothly connect two keyframes, filling in the motion so the transition looks natural rather than jumpy.

What is rigging in 3D animation?

Rigging is the process of building a digital skeleton, along with controls, inside a 3D character model. This rig allows an animator to pose and move the character's limbs, face, and body realistically, without needing to reshape the model manually for every frame.

What is the difference between motion capture and rotoscoping?

Motion capture records the actual movements of a real actor using sensors, then applies that data directly to a digital character. Rotoscoping instead has an animator manually trace over live-action footage frame by frame, producing a more stylised but still realistic result.

What is a storyboard used for?

A storyboard is a series of drawings showing the planned shots, actions, and camera angles of a scene before full animation begins. It helps a director and team plan pacing and composition early, avoiding costly changes later in production.

What is compositing?

Compositing is the process of combining multiple separate visual elements — such as characters, backgrounds, lighting effects, and text — into a single finished image or shot. It is often one of the final steps before a scene is considered complete.

What does easing mean in animation?

Easing refers to the gradual acceleration or deceleration of a moving object or character, rather than constant, mechanical-looking speed. Natural motion in the real world almost always eases in and out, so animators add this effect to make movement feel believable.

What is stop-motion animation?

Stop-motion is a technique where physical models, puppets, or objects are moved slightly and photographed one frame at a time. When played back in sequence, these individual photographs create the illusion of continuous movement.

Is animation vocabulary useful for English learners?

Yes, especially for learners interested in film, gaming, or digital media, since animation vocabulary appears in production credits, tutorials, and behind-the-scenes documentaries. Many terms, like rendering and timeline, are also used more broadly in digital creative software.

Which animation words should I learn first?

Start with the basics: animator, frame, keyframe, and storyboard. Then learn technical production terms such as rigging, rendering, compositing, and motion capture, which describe how a finished animated scene is created.
