1
machine that collides particles
A big science machine that makes tiny particles hit each other.
Patrón de uso:
a collider; build/operate [a collider]
Error frecuente:
Learners may confuse collider with collision (the crash itself) or collusion (secret cooperation).
Sinónimos
particle accelerator (Broader term; not all accelerators are designed for head-on collisions.)
Colocaciones
particle collider
|hadron collider
|high-energy collider
|collider experiment

Ejemplos
- 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.
Ejemplos para estudiantes

collision-detection component in software
In a game, a collider is a shape that lets objects bump into things correctly.
Patrón de uso:
add/attach [a collider] to [an object]
Error frecuente:
Often confused with rigidbody/physics body; a collider detects contact, while a physics body controls movement and forces.
Sinónimos
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.)
Colocaciones
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
Temas

|software
|gaming
Ejemplos
- 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.
Ejemplos para estudiantes
- 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.
Patrón de uso:
condition/adjust/control for [a collider]
Error frecuente:
Learners often mix up collider with confounder; a confounder causes both variables, while a collider is caused by both.
Sinónimos
collider node (Same concept, emphasizing its role as a node in a causal graph.)
Antónimos
confounder (A common cause, not a common effect; adjusting for it often reduces bias rather than creating it.)
Colocaciones
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
Temas

Ejemplos
- 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.
Ejemplos para estudiantes
- Do not control for a collider in this model.

4
thing that collides
A thing that hits another thing.
Patrón de uso:
the collider; the [first/second] collider
Error frecuente:
This sense is uncommon; most contexts prefer vehicle, car, or object instead of collider.
Sinónimos
impacting object (More general and clearer in most writing.)
Colocaciones
the primary collider
|the secondary collider
|two colliders
|the approaching collider
|collider speed
|collider mass
Temas
transport
|accidents
Ejemplos
- Investigators estimated the collider’s speed from skid marks and vehicle damage.
- In the simulation, the collider struck the barrier at a shallow angle.

fixed phrase
technical
rectangular collision shape in games
A square/rectangle-shaped collider in a game engine.
Ejemplos
- 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.
Ejemplos
- 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.

technical
variable caused by two factors
A result variable that has two causes.
Ejemplos
