What Is the Difference Between Affect and Effect?
Affect and effect are examples of homophones – two words that sound alike but have different meanings and spellings. People frequently confuse the two words because we often use affect and effect in similar contexts.
This blog post will explore the difference between affect and effect and help you know which one to use – whether you’re editing, proofreading, or writing.
What’s the Difference Between Affect and Effect?
To put it simply, affect is usually a verb that means “to impact or change.” On the other hand, we normally use effect as a noun, and it means “the result or consequence of a change.”
Consider a simple scenario: You go for a walk in the rain and get wet. The rain affects you. The effect of the rain is that you get wet.

If the word you’re using is a verb, it’s most likely affect:

We use affects as the present tense form of the verb:

We use affected as the past tense form:
Her inspiring speech affected my mood positively.
And we use affecting as the present continuous form of the verb:

When to Use Effect
If the word you need is a noun, effect is the right choice:

We can use effects as the plural form of the noun:

The film and theater industries also commonly use effects:
