See explanation, which may affect your understanding to good effect...


Affect is a transitive verb saying that A causes a change in B.

For example: Salt affects blood pressure.

Effect is usually a noun expressing a change.

For example: The effect of eating too much salt is often elevated blood pressure.

Effect can also be a verb, when it means something like "to bring into being" or "to cause to happen".

For example: He effected his doctor's recommendation to reduce his blood pressure by reducing his salt intake.

"Effect" is a noun and "Affect" is a verb.


Two words "effect" and "affect" have similar concepts to influence something. However, their parts of speech are different.

[Affect] is a verb. Acording to Longman Dictionary of Contemporary English, affect means "to do something that produces an effect or change in something or in someone’s situation" and so on.

On the contrary, [Effect] is a noun. Its definition is "a change that is caused by an event, action etc".

An ecological system can be affected by the greenhouse effect.
