Prepositions after verbs

Fire from, at, on, by or in?

Fire combines with different prepositions depending on direction, position, method, or topic. Some combinations are uncommon or limited to special contexts.

Quick answer

Which preposition is used with fire?

Common mistakes

Some combinations appear in real text but do not mean what learners often assume.

Using fire at for the source

Use fire from for the place or weapon.

✕ The rocket was fired at the ship. ✓ The rocket was fired from the ship.

Using fire by as a shooting pattern

Fire by is not a normal combination meaning shoot at something.

✓ The guard fired at the door.

Confusing fire on and fire at

Fire on is more formal and often military.

✓ The officer ordered the troops to fire on the bunker.

Treating in as the object preposition

In usually describes location or direction, not the target.

✕ They fired in the suspect. ✓ They fired at the suspect.

Quick practice

Choose the expression that matches the intended meaning.

1. The police fired ___ the suspect's car.
2. The missile was fired ___ a naval ship.
3. The commander ordered soldiers to fire ___ the enemy line.
