To That Effect vs Affect: Which Phrase Is Correct?

“To that effect” is correct. “To that affect” is incorrect in standard English. The word effect is a noun in this phrase. It means “meaning,” “result,” “message,” or “general idea.” The word affect is usually a verb, so it does not fit the phrase.

Correct:

• He said something to that effect.
• The email included a sentence to that effect.
• She made a comment to that effect.

Incorrect:

• He said something to that affect.
• The email included a sentence to that affect.

What Does “To That Effect” Mean?

“To that effect” means “with that meaning” or “with that general message.” It is used when the exact words are not repeated, but the meaning is the same.

Example:

• He said the meeting was cancelled, or words to that effect.

This means he may not have used the exact words “the meeting was cancelled,” but his message had that meaning.

More examples:

• The manager said the budget was too high, or something to that effect.
• The report stated that sales were falling, or words to that effect.
• She told me the offer had expired, or a message to that effect.

The phrase helps when the speaker remembers the meaning but not the exact wording.

Is “To That Affect” Correct?

No, “to that affect” is not correct. The correct phrase is to that effect.

The mistake happens because effect and affect sound similar. Their meanings are different.

Correct:

• The rule had a strong effect.
• The weather can affect travel.

In the phrase to that effect, the sentence needs a noun. That noun is effect, not affect.

Why Is “Effect” Correct in “To That Effect”?

“Effect” is correct because the phrase refers to the meaning, result, or message of a statement. The phrase does not describe the action of influencing something.

In simple terms:

• to that effect = with that meaning
• to that affect = wrong phrase

Example:

• The lawyer sent a notice to that effect.

This means the notice carried that message or produced that meaning.

It does not mean the notice influenced something “to that affect.” That structure does not work.

What Is the Difference Between Effect and Affect?

Effect is usually a noun, and affect is usually a verb. This is the main difference.

Use effect when you mean a result.

Examples:

• The medicine had an effect.
• The law had a major effect.
• The speech had no effect on the crowd.

Use affect when you mean influence or change.

Examples:

• The medicine can affect sleep.
• The law can affect workers.
• The speech affected the crowd.

Simple rule:

• Effect = result
• Affect = influence
