Antonyms

Grammar Patterns

key actor in [situation]

actor on the [scene/stage]

Usage Note

Distinguish from sense 1: this sense almost always appears with a defining phrase such as 'in [the conflict/market/process]' or with adjectives like 'key', 'major', 'state', 'non-state'. Subjects are often institutions or countries, not individual people.

Common Mistakes

He is an actor in our company decisions.
He plays an active role in our company decisions.
for a single person at work, prefer 'play a role'; 'actor' here sounds odd outside formal political or social analysis.

3.nounB2
Definition

someone who behaves in a fake way to hide what they really feel or think, so that other people believe a different version of them.

Example

Don't trust Quinn's tears — she's a brilliant actor when she wants something.

brilliant/good + actor (deception)

Greta is such a bad actor that everyone could see she was lying about the broken vase.

such a + bad actor

Common collocations
  • good actor
  • bad actor
  • brilliant actor
  • such an actor
Synonyms
  • pretender

    more negative — suggests deliberate dishonesty

  • fake

    stronger and informal — labels the person, not just the behaviour

Grammar Patterns

a good/terrible actor

such an actor

Usage Note

Almost always preceded by an evaluating adjective ('good', 'bad', 'terrible', 'brilliant') or 'such a/an'. Without that adjective the listener will assume sense 1 (a professional actor).

Common Mistakes

She is an actor when she pretends to be happy.
She is a good actor when she pretends to be happy.
this sense almost always needs a judging adjective; bare 'an actor' will be heard as the job.

Word family

Synonym discussion

Sense: noun/1

All four words describe people who appear before an audience, but they differ in scope and tone. 'Actor' is the everyday, gender-neutral choice for someone who plays a character in a film, play, or TV show — Imani, who studies drama at school, will simply call herself an actor. 'Performer' is broader: it covers singers, dancers, magicians, and stand-up comedians, so a circus 'performer' is not necessarily an actor. 'Actress' was once the standard female form and still appears in award categories (Best Actress), but in everyday speech and journalism it is fading; many women in the industry now prefer 'actor'. 'Thespian' is literary or slightly playful, almost always tied to the stage, so a Shakespeare festival programme might describe its cast as 'thespians', but a cinema poster never would.

Etymology

LatinOld FrenchMiddle EnglishModern English

Borrowed in the late 14th century from Latin 'actor', meaning 'a doer' or 'one who carries something out', formed from the verb 'agere' (to do, to drive). At first English used it in the 'doer' sense — a person who performs an action, including in legal contexts (a plaintiff). The theatrical meaning grew during the 1500s as professional playhouses appeared, and from the 1900s 'actor' also stretched into political and social analysis to label any person or group whose actions move events along.
