Comprehensive Actors Glossary of Terms

Whether you’re just starting or brushing up on industry knowledge, this glossary covers the essential terms every actor should know, from the classroom to the audition room to the set.

Acting Techniques & Methods

Method Acting: A technique where actors draw on their own personal experiences and emotional memories to bring deep authenticity to their roles.
Emotional Memory (Affective Memory): A tool within Method Acting where an actor recalls a personal emotional experience to generate genuine feeling in a scene.
Sense Memory: A related exercise where an actor recalls physical sensations — temperature, smell, texture — to ground a performance in physical reality.
Stanislavski System: The foundational method developed by Konstantin Stanislavski, focusing on the psychological and emotional truth of a character through objectives, actions, and given circumstances.
Meisner Technique: Developed by Sanford Meisner, this approach trains actors to live truthfully in imaginary circumstances, emphasizing listening and reacting genuinely to scene partners in the moment.
Ivana Chubbuck Technique: A 12-step method that channels an actor’s personal pain and inner drive into their character’s pursuit of a goal. The technique focuses on using real emotion as fuel to power objective-driven, powerful performances.
Chekhov Technique: Developed by Michael Chekhov, this method focuses on physical and psychological gestures, imagination, and atmosphere to access and express character from the outside in.
Uta Hagen’s Object Exercises: Exercises designed to help actors create believable behavior by grounding themselves in specific, real interactions with objects and their environment.
Practical Aesthetics: Developed by David Mamet and William H. Macy, this technique strips away psychological complexity in favor of clear, playable actions — focusing on what the character is literally doing in a scene.
Spolin Improvisation: A system developed by Viola Spolin using theater games and spontaneous play to develop presence, ensemble awareness, and creative freedom in actors.
Suzuki Method: A rigorous physical training method developed by Tadashi Suzuki that builds an actor’s presence, discipline, and stamina through intense movement exercises rooted in Japanese theatrical traditions.
Viewpoints: A technique involving the analysis of movement, time, space, and gesture to build physical, ensemble-based performance.
Alexander Technique: A method that teaches actors to release physical tension and use their bodies more efficiently and naturally, improving posture, breath, and vocal freedom.
Laban Movement Analysis: A system for understanding and describing human movement through effort, space, shape, and body, used to help actors build distinct physical lives for characters.

Character & Script Analysis

Objective: What a character wants in a specific scene. Often phrased as “I want to…” — the driving force behind every moment of action.
Super Objective: The overarching goal or deepest want of a character throughout the entire play or film — the through-line of their desire.
Action: What the character is actively doing to get what they want. Actions are playable, transitive verbs — e.g., “to seduce,” “to warn,” “to comfort.”
Tactics: The specific strategies or approaches a character uses moment to moment to pursue their objective. When one tactic fails, they shift to another.
Obstacle: What stands between the character and their objective — internal (fear, doubt) or external (another person, circumstance). Obstacles create conflict and drama.
Given Circumstances: The specific facts, conditions, and history that define the world of the play — who the character is, where they are, what has happened before the scene begins.
Subtext: The unspoken meaning beneath a character’s words and actions — what they really mean, feel, or want beneath the surface of what they say.
Beat: A unit of action within a scene where a shift or change occurs — a new objective, tactic, or emotional moment begins.
Arc: The development or transformation of a character over the course of the story — how they change from beginning to end.
Through-Line (Spine): The central thread connecting all of a character’s choices throughout the story — the continuous inner logic that drives every scene.
Motivation: The underlying reason behind a character’s actions and decisions — the “why” that fuels their behavior.
Backstory: The history of a character’s life before the events of the story — used to inform present behavior and choices.
Endowment: Actively attributing imagined qualities, history, or meaning to objects, places, or other characters to deepen the reality of a scene.
Status: The relative power dynamic between characters in a scene. Playing high or low status affects physicality, voice, and behavior — and can shift moment to moment.
Off Book: When an actor has their lines fully memorized and no longer needs to refer to a script during rehearsal.
On Book: When an actor is still working from or referring to the script during rehearsal.

Performance & Stage

Fourth Wall: The imaginary boundary between the performers and the audience. When an actor acknowledges the audience directly, they are said to “break the fourth wall.”
Aside: A line of dialogue spoken directly to the audience that the other characters onstage are not supposed to hear.
Soliloquy: A speech delivered by a single actor alone on stage, often revealing their inner thoughts directly to the audience.
Monologue: A long speech delivered by one actor, either to other characters or the audience, in a play or film.
Projection: The technique of using voice and breath to be heard clearly throughout a space without shouting.
Physicalization: Using the body — posture, gesture, movement — to express a character’s inner life, emotion, or status.
Pace: The speed at which a scene unfolds or lines are delivered. Adjusting pace is a key tool for building tension, comedy, or emotional weight.
Improvisation: Performing spontaneously without a script, making up dialogue and action in the moment. A core skill for auditions, collaboration, and creative development.
Ad-lib: Going off-script to improvise a line or moment — whether intentional or as a response to an unexpected situation.
Cue: A signal — verbal, physical, or technical — for an actor to begin their lines or action.
Upstaging: When an actor draws focus away from the intended main action, or when a more upstage position forces another actor to turn their back to the audience.
Cheating Out: Subtly adjusting your body position to face the audience or camera more directly, without it appearing unnatural.
Breaking Character: Losing immersion in a role — stepping out of the fiction of the scene, whether accidentally or intentionally.
Playing Against: Performing the emotional opposite of what the text suggests — e.g., laughing when discussing something painful — to create nuance and subtext.
Stage Whisper: A loud, theatrical whisper meant to be heard clearly by the audience, while maintaining the pretense that other characters cannot hear it.
Emoting: Expressing emotion outwardly in performance. When overdone without grounding, it becomes “mugging.”
Mugging: Overacting or making exaggerated facial expressions, usually for comic effect but often at the expense of truth.
Milking: Deliberately extending a moment or reaction for maximum dramatic or comedic effect.
Downstage: The area of the stage closest to the audience.
Upstage: The area of the stage farthest from the audience.
Stage Left / Stage Right: Directions from the actor’s perspective while facing the audience. Stage left is to the actor’s left; stage right is to the actor’s right.
Opening Up: Turning your body toward the audience to be more visible and engaged with the house.
Closing Off: Turning away from the audience, often accidentally — something directors will correct.
Places: The command given to performers to take their assigned starting positions before a scene or performance begins.
