“The action is affect; the end result is effect.”
- Barbara Wallraff, Word Court. Harcourt, 2000

Affect as a verb means "to influence", while effect means "to bring about".

Note: Effect is often used in an adjective or noun phrase:
- After effect
- Cause and effect
- Domino effect
- Greenhouse effect
- Personal effects
- Side effects
- Sound effect
- Special effect

Practise using affect and effect in a sentence:

These examples have been taken from news headlines.

1. Smoking legislation to affect drivers

2. 5 Facebook rulings that affect what Canadians can do online

3. Cardamom crops affect forests, studies say

4. Changes in the temperature of foods can affect taste intensity

Test yourself by rewriting these headlines using the word effect.

Sentence #3 has been rewritten about the end results instead of an action and is used as a noun: The effects of cardamom crops are detrimental to tropical forests.

Affect as a noun

On rare occasions, affect is used as a noun in reference to a person’s mental state or display of emotion.

For example, when speaking about a depressed patient’s emotional response to stimuli you might say they showed a flat affect to stimuli.

Effect as a verb

When used as a verb, effect means having the power to bring about or to accomplish something. This is similar to its meaning as a noun ("end result").

Example: the principal wanted to effect a change in the school’s curriculum.
