Synonym Chooser

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

Some common synonyms of impact are collision, concussion, and shock. While all these words mean "a forceful, even violent contact between two or more things," impact may be used to imply contact between two things, at least one of which is impelled toward the other.

When is it sensible to use collision instead of impact?

The meanings of collision and impact largely overlap; however, 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 impact?

In some situations, the words concussion and impact are roughly equivalent. However, 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 shock be used to replace impact?

The synonyms shock and impact are sometimes interchangeable, but shock often denotes the effect produced by a collision and carries the suggestion of something that strikes or hits with force.
