1.verbtransitiveC2
Definition

to choose actors for the characters of a stage or screen production, or to select every performer needed for that production.

Example

The director cast a young actor from Seoul in the lead role.

cast [actor] in [role]

After months of searching, the producers cast Arjun as the villain.

cast [actor] as [character]

Common collocations
  • cast in the role of
  • cast as
  • cast the lead
  • well cast
  • badly cast
Synonyms
  • choose

    more general; 'choose' does not specifically refer to theatrical selection

  • select

    more formal; equally neutral about the domain

  • appoint

    suggests a formal, official decision rather than an artistic one

Grammar Patterns

cast + actor + as + role

cast + actor + in + role

be + cast as + role

Usage Note

Frequently used in the passive ('She was cast as the hero') or in the pattern 'cast [actor] in/as [role].' The direct object can be the production itself ('cast the film'), but more commonly it is the performer.

Common Mistakes

The director cast him as the movie.
The director cast him as the hero in the movie.
'cast' with 'as' takes the role or character type, not the production name.
The director casted her in the lead role.
The director cast her in the lead role.
'cast' is irregular; the past form is 'cast', not 'casted'.

2. to make light, shade, or a glow appear on or across a surface.

2.verbtransitiveC2
Definition

to make light, shade, or a glow appear on or across a surface.

Example

The setting sun cast long shadows across the garden wall.

cast + shadow + across [surface]

A single reading lamp cast a warm glow over the old wooden desk.

cast + glow

Common collocations
  • cast a shadow
  • cast light
  • cast a glow
  • cast darkness
  • cast shade
Synonyms
  • throw

    more informal; 'throw light' is common but 'throw a shadow' is rarer than 'cast a shadow'

  • project

    more technical; often used for projected images rather than natural light

Antonyms
  • absorb

    opposite action; a surface that absorbs light does not cast it

Grammar Patterns

cast + [light/shadow] + prepositional phrase

Usage Note

The direct object is nearly always a light-related noun: 'light,' 'shadow,' 'glow,' 'darkness,' 'shade.' Frequently followed by a prepositional phrase with 'on,' 'over,' 'across,' or 'into' that tells where the light or shadow falls. This sense is typically literal; for the metaphorical use, see sense 3.

Common Mistakes

The lamp casted a shadow on the wall.
The lamp cast a shadow on the wall.
'cast' is irregular; past tense is 'cast', not 'casted'.

3. to provide information or an explanation that helps people understand a difficul

3.verbtransitiveB2
Definition

to provide information or an explanation that helps people understand a difficult situation, problem, or mystery.

Example

The old letters cast new light on what happened before the war.

cast light on [topic]

Brooke's research could cast light on why some children develop the allergy.

Common collocations
  • cast light on
  • shed light on
  • cast new light on
  • cast fresh light on
Synonyms
  • clarify

    more direct; 'cast light on' is more idiomatic and descriptive

  • explain

    simpler and broader; 'cast light on' suggests revealing something previously hidden

  • illuminate

    more formal; shares the visual metaphor of 'light'

Antonyms
  • obscure

    to make something harder to understand, the opposite of explaining

  • confuse

    to cause misunderstanding rather than clarity

Grammar Patterns

cast + light + on + [topic]

Usage Note

Only used in the fixed phrase 'cast light on' (or the more common variant 'shed light on'). The object of 'on' is always the thing being explained — a mystery, situation, problem, or question. Never used transitively with a direct object outside this phrase pattern.

Common Mistakes

The report cast light the problem.
The report cast light on the problem.
the preposition 'on' is required after 'light' in this phrase.
The discovery cast a light on the case.
The discovery cast light on the case.
when used metaphorically, 'light' is usually uncountable (no article).

4. to direct a look, smile, or other expression toward someone or something with a

4.verbtransitiveB2
Definition

to direct a look, smile, or other expression toward someone or something with a particular feeling.

Example

Élise cast a worried look at her brother as the storm grew louder.

cast a [adjective] look at [person]

The teacher cast a suspicious glance around the exam room.

Common collocations
  • cast a look
  • cast a glance
  • cast a smile
  • cast an eye
Synonyms
  • direct

    less idiomatic; 'direct a look at' is more neutral in register

  • turn

    simpler; 'turn a look toward' is common but less vivid

Grammar Patterns

cast + [a look/glance/smile] + at/toward/around + [person/place]

Usage Note

The direct object is always a word for an expression or look: 'look,' 'glance,' 'smile,' 'eye.' The feeling carried by the look is described by an adjective before that noun. Typically followed by a preposition like 'at,' 'toward,' 'around,' or 'over.' Distinguish from sense 5, which specifically means a quick examination of a document or object.

Common Mistakes

❌ 'She cast him a suspicious look.' — This pattern (indirect object + direct object) is actually acceptable in informal English, though 'She cast a suspicious look at him' is more standard in writing.

5. to give a brief, hasty look at something such as a written page, without reading

5.verbtransitiveB2
Definition

to give a brief, hasty look at something such as a written page, without reading it carefully.

Example

Could you cast an eye over my essay before I hand it in tomorrow?

cast an eye over [document]

Sumin cast a quick glance at the report and spotted two errors.

cast a quick glance at [thing]

Common collocations
  • cast an eye over
  • cast a glance at
  • cast one's eyes over
Synonyms
  • glance at

    simpler and more common in everyday speech

  • scan

    suggests looking for specific information rather than a casual look

  • skim

    specifically about reading quickly without full attention

Antonyms
  • study

    to look at something with full attention and care

  • examine

    to inspect thoroughly, the opposite of a quick look

Grammar Patterns

cast + an eye + over + [document]

cast + a glance + at/over + [thing]

Usage Note

Common in the fixed phrases 'cast an eye over' and 'cast a glance at/over.' The object of the preposition is what gets examined — never the direct object of 'cast.' Distinguish from sense 4: sense 4 is about directing an expression with feeling toward someone, while sense 5 is about a quick, practical examination of something.

Common Mistakes

Please cast an eye the contract before you sign.
Please cast an eye over the contract before you sign.
the preposition 'over' (or 'at') is required after 'eye'.

6. to send video, audio, or other media from a computer, phone, or tablet to a scre

6.verbtransitive / intransitiveB1
Definition

to send video, audio, or other media from a computer, phone, or tablet to a screen or speaker over a wireless connection.

Example

Dewi cast the movie from her phone to the living room television.

cast [content] from [device] to [device]

The app lets you cast photos directly to any screen in the house.

Common collocations
  • cast to
  • cast from
  • cast audio
  • cast video
  • cast screen
Synonyms
  • stream

    broader term; 'stream' can mean play over the internet, while 'cast' specifically suggests sending from one device to another nearby

  • send

    simpler but less specific; does not imply the wireless screen-mirroring technology

Grammar Patterns

cast + [content] + to + [device]

cast + to + [device]

Usage Note

Can be used transitively ('cast the video to the TV') or intransitively ('The app casts easily'). The preposition 'to' introduces the receiving device. Common in technology contexts and growing in everyday use. The past form remains 'cast' ('She cast the video yesterday'), not 'casted.'

Common Mistakes

I casted the video to my TV.
I cast the video to my TV.
'cast' is irregular; the past form is always 'cast' regardless of sense.
Cast the video on the TV.
Cast the video to the TV.
in the technology sense, 'to' is the standard preposition indicating the destination device.

More formal and literary than throw. The direction must be stated using a preposition such as into, at, across, or toward.

Common Mistakes

I casted the net into the water.
I cast the net into the water.
Cast is an irregular verb; its past form is cast, not casted.

Grammar Patterns

cast + object + on/over + someone

Usage Note

The direct object is almost always a noun that names a specific type of magic — such as 'spell', 'curse', or 'charm'. Using 'cast magic' alone is much less common and sounds unnatural to many native speakers.

Common Mistakes

The magician cast a magic on the audience.

Synonym discussion

Sense: verb/7

Cast, throw, toss, hurl, and fling all describe sending something through the air, but they differ in register, force, and context. Cast is the most formal and literary of the group; you would use it in writing ('The fisherman cast his net') or in fixed expressions ('cast a vote', 'cast a shadow'), but less often in casual conversation. Throw is the everyday, neutral word and can be used in almost any context ('She threw the ball to her brother'). Toss suggests a light, casual, or gentle motion, often over a short distance ('He tossed the keys onto the table'). Hurl and fling both imply great force or strong emotion: hurl suggests aggressive, forceful throwing ('The protester hurled a bottle at the police'), while fling suggests a more impulsive, sweeping motion often driven by anger or desperation ('She flung her bag onto the bed and stormed out'). In zh-TW, cast corresponds to 投 (formal/literary), throw to 扔 (neutral/colloquial), toss to 輕拋 (gentle), hurl to 猛擲 (violent), and fling to 甩 (impulsive). For learners, remember: cast is the word for formal contexts and fixed collocations; throw covers most everyday situations; toss, hurl, and fling add specific nuances of weight, force, and emotion.

Etymology

Old NorseMiddle EnglishEnglish

Cast comes from Old Norse kasta meaning 'to throw', which entered Middle English in the 13th century. The original sense of physically throwing something gave rise to numerous metaphorical extensions that emerged over the following centuries: directing a look, emitting light or shadow, recording a vote, assigning actors to roles, and forming molten metal in a mould. The notion of 'sending forth' or 'projecting' unites all these modern uses. The Old English equivalent weorpan (to throw) was gradually replaced by cast under Scandinavian influence.
