Synonym Chooser

How is the word collision different from other nouns like it?

Some common synonyms of collision are concussion, impact, and shock. While all these words mean "a forceful, even violent contact between two or more things," collision implies the coming together of two or more things with such force that both or all are damaged or their progress is severely impeded.

the collision damaged the vehicle

In what contexts can concussion take the place of collision?

The synonyms concussion and collision are sometimes interchangeable, but concussion when not in technical use, often suggests the shattering, disrupting, or weakening effects of a collision, explosion, or blow.

bystanders felt the concussion of the blast

When could impact be used to replace collision?

In some situations, the words impact and collision are roughly equivalent. However, impact may be used to imply contact between two things, at least one of which is impelled toward the other.

the glass shattered on impact with the floor

When might shock be a better fit than collision?

The words shock and collision are synonyms, but do differ in nuance. Specifically, shock often denotes the effect produced by a collision and carries the suggestion of something that strikes or hits with force.

the shock of falling rocks
