Is It Take Effect or Take Affect?
Let’s clear it up immediately:
✅ Correct: take effect ❌ Incorrect (almost always): take affect
So if your question is:
Is it take effect or take affect?
The correct phrase is “take effect.”
“Take effect” is a standard English expression meaning something becomes active, begins to apply, or starts producing results—like a new law, a policy, or medicine.
What Does “Take Effect” Mean?
The phrase take effect means:
- to begin to work
- to become active
- to start producing results
- to be enforced
- to come into action
In simple words: when something takes effect, it is no longer just an idea—it becomes real, operational, and applicable.
Common real-life contexts where “take effect” is used
- Law: “The new law will take effect next month.”
- Policies: “The updated policy takes effect on March 1.”
- Medicine: “This medicine takes effect in 30 minutes.”
- Rules: “The rules take effect immediately.”
- Decisions: “The decision will take effect after approval.”
Why “Take Affect” Is Usually Wrong
Most of the time, “take affect” is simply a typo or grammar mistake.
That’s because:
- Affect is usually a verb
- Effect is usually a noun
And the phrase take effect needs a noun after “take,” because “take” is acting like a verb that receives an object.
So:
- “take effect” ✅ (effect = noun)
- “take affect” ❌ (affect is usually a verb, not used like this)
Affect vs Effect: The Real Grammar Rule (Simple & Powerful)
This is the #1 rule you should remember:
✅ Affect = Verb (Action)
Affect means to influence or impact something.
Examples:
- “Stress can affect your health.”
- “The weather may affect the match.”
✅ Effect = Noun (End Result)
Effect means the result, outcome, or consequence.
Examples:
- “The medicine had a strong effect.”
- “The new rule had no effect on sales.”
The Best Memory Trick (Never Forget Again)
Here’s the easiest trick:
- Affect = Action
- Effect = End result
Once you keep this in mind, choosing the right word becomes effortless.

Can “Affect” Ever Be Correct? (Rare Exception Explained)
Yes—but not in the phrase “take affect.”
Affect as a noun (rare usage)
In psychology, affect can be used as a noun meaning emotion or visible emotional expression.
You might see:
- “flat affect”
- “blunted affect”
- “emotional affect”
However, even in this meaning, we still don’t say “take affect.” So for everyday writing, school, blogging, emails, and professional writing, you can safely treat take affect as incorrect.
Can “Effect” Be a Verb? (Advanced but Important)
Yes! This is where English gets interesting.
Effect can also be used as a verb meaning:
- to bring about
- to cause
- to make something happen
Example:
- “The manager worked to effect change in the company.”
- “The policy was designed to effect improvement in safety.”
But does that change “take effect”?
No.
Even though “effect” can be a verb in special cases, the expression take effect remains the correct and widely accepted phrase.
