1
machine that collides particles
A big science machine that makes tiny particles hit each other.
Schéma d’usage :
a collider; build/operate [a collider]
Erreur fréquente :
Learners may confuse collider with collision (the crash itself) or collusion (secret cooperation).
Synonymes
particle accelerator (Broader term; not all accelerators are designed for head-on collisions.)
Collocations
particle collider
|hadron collider
|high-energy collider
|collider experiment
|collider facility
|collider ring
|collider tunnel
|collider physics
|collider data
|collider results
Thèmes
science
|physics
|technology
Exemples
- The new collider will help researchers study how matter behaves at extremely high energies.
- Data from the collider revealed a rare particle decay that matched the team’s predictions.
- Engineers upgraded the collider to increase the number of collisions per second.
Exemples pédagogiques
- Scientists use a collider to study tiny particles.
- The collider is a very large machine.

collision-detection component in software
In a game, a collider is a shape that lets objects bump into things correctly.
Schéma d’usage :
add/attach [a collider] to [an object]
Erreur fréquente :
Often confused with rigidbody/physics body; a collider detects contact, while a physics body controls movement and forces.
Synonymes
collision shape (Common descriptive synonym; not always the official name in an engine.)
|
hitbox (More informal; often used for combat/target areas rather than full physics.)
Collocations
add a collider
|attach a collider
|enable the collider
|disable the collider
|trigger collider
|collision mesh collider
|box collider
|sphere collider
|capsule collider
|collider bounds
Thèmes
computing
|software
|gaming
Exemples
- Add a collider to the character so it can’t walk through walls.
- The projectile uses a small sphere collider to detect hits accurately.
- If the collider is marked as a trigger, objects can pass through but still register contact events.
Exemples pédagogiques
- I added a collider to the door.
- The ball’s collider is too big.

3
common-effect variable in causal graphs
In causal graphs, a collider is a result of two causes, and controlling for it can create bias.
Schéma d’usage :
condition/adjust/control for [a collider]
Erreur fréquente :
Learners often mix up collider with confounder; a confounder causes both variables, while a collider is caused by both.
Synonymes
collider node (Same concept, emphasizing its role as a node in a causal graph.)
Antonymes
confounder (A common cause, not a common effect; adjusting for it often reduces bias rather than creating it.)
Collocations
collider variable
|collider node
|condition on a collider
|adjust for a collider
|control for a collider
|collider bias
|collider stratification
|open a path at a collider
|blocked by a collider
|DAG collider
Thèmes
statistics
|data_science
|academia
Exemples
- In the diagram, hospital admission is a collider because it is affected by both illness severity and access to care.
- Adjusting for a collider can make two unrelated variables appear correlated.
- The analyst avoided conditioning on the collider to prevent introducing bias.
Exemples pédagogiques
- Do not control for a collider in this model.

4
thing that collides
A thing that hits another thing.
Schéma d’usage :
the collider; the [first/second] collider
Erreur fréquente :
This sense is uncommon; most contexts prefer vehicle, car, or object instead of collider.
Synonymes
impacting object (More general and clearer in most writing.)
Collocations
the primary collider
|the secondary collider
|two colliders
|the approaching collider
|collider speed
|collider mass
Thèmes
transport
|accidents
Exemples
- Investigators estimated the collider’s speed from skid marks and vehicle damage.
- In the simulation, the collider struck the barrier at a shallow angle.

Expressions
box collider
1/bˈɑks kəlˈaɪdɚ/
fixed phrase
technical
rectangular collision shape in games
A square/rectangle-shaped collider in a game engine.
Exemples
- Use a box collider for the platform to keep the physics calculations simple.
- The crate’s box collider didn’t match the model, so the player kept snagging on the edges.
collider bias
1/kəlˈaɪdɚ bˈaɪəs/
fixed phrase
technical
bias from conditioning on a collider
A mistake in analysis caused by controlling for a collider.
Exemples
- Selecting only patients who visited the hospital can introduce collider bias in observational studies.
- The researchers discussed collider bias as a possible explanation for the unexpected correlation.
collider variable
1/kəlˈaɪdɚ vˈɛɹiəbəl/
fixed phrase
technical
variable caused by two factors
A result variable that has two causes.
Exemples
- If treatment and risk both affect dropout, then dropout is a collider variable.
- The paper warns against adjusting for a collider variable when estimating the causal effect.
