Hello,

Does anyone know of a good way to explain the difference between these two nouns:

impact

effect

Are there times when you could use one, but not the other?

Any examples or explanations would be greatly appreciated.

Sincerely,

SC

Do not confuse the words affect, effect, and impact, each of which can be used both as a verb and as a noun. Avoid incorrectly using impact as a verb in place of affect or as a noun in place of effect.

Affect as a verb means "to influence."
Affect as a noun has a specialized meaning in medicine and psychology, referring to moods and feeling as distinct from thoughts or knowledge.


Effect as a verb means "to bring about, to produce," or to "accomplish something."
Effect as a noun means "result."

Impact as a verb means "strike with a blow" or "to pack firmly together."
Impact as a noun means "a collision."

Do not use impact as a verb in place of "to affect", do not use impact as a noun in place of "effect."
