The phrase “to that effect or affect” often confuses English learners because both words sound similar but serve completely different grammatical roles.
Many writers are unsure whether to use affect or effect when forming sentences that summarize meaning or intent.
This confusion usually appears in formal writing, emails, and academic texts where precision matters.
In this guide, we will clearly explain the correct usage of to that effect or affect, break down the difference between the two words, and show real examples so you never mix them again. You will also learn common mistakes and a simple trick to remember the right choice.
Quick Answer
The correct phrase is “to that effect”, not “to that affect.”
We use “to that effect” when we refer to something said or written in a similar meaning.
👉 Example: He said the project is delayed, or words to that effect.
❌ “To that affect” is incorrect because affect (verb) means to influence something, not to express meaning. The correct noun form is effect.
Why People Get Confused Between Affect and Effect
The confusion comes from similar pronunciation and overlapping usage in writing. In English Grammar, learners often struggle because both words look related but follow different grammatical roles.
- Affect (verb) → to influence something
- Effect (noun) → the result of something
This difference becomes even harder in phrases like “to that effect,” where only the meaning-based word fits.

It belongs to formal English Writing and is commonly used in reports, emails, and academic summaries.
