What Does “Take Effect” Mean?
“Take effect” is the correct phrase in English. It means something begins to work or starts having results. You can think of it as the moment when a law, rule, decision, or plan starts producing its intended result.
Example definitions in plain English:

- Plan or agreement: “The new schedule takes effect immediately.”
Key points:

Why “Take Affect” Is Incorrect
Many people mistakenly write “take affect” instead of “take effect”. The reason is simple: “affect” is a verb meaning to influence or change something, while “effect” is usually a noun meaning result or outcome.
Incorrect:
- “The new policy will take affect tomorrow.”
Correct:
- “The new policy will take effect tomorrow.”
Tip to remember:
Think of effect = result, which fits perfectly after “take.”
Affect is a verb and doesn’t match grammatically after “take.”
