To this affect or to this effect: Understanding the Correct Phrase and Its Usage
When writers encounter the expression to this affect versus to this effect, hesitation often follows. Consider this: the subtle difference between affect and effect trips up native speakers and learners alike, leading to frequent misuse in both casual conversation and formal writing. This article clarifies which form is grammatically correct, explains the underlying distinction between the two homophones, provides abundant examples, and offers practical tips to avoid the mistake in the future. By the end, you will confidently choose to this effect and understand why to this affect is considered an error in standard English.
Introduction: Why the Confusion Matters
The phrase to this effect appears in legal documents, academic papers, business correspondence, and everyday speech to indicate that something is done with the purpose of achieving a particular result or in accordance with a stated intention. Worth adding: for instance, a manager might say, “We issued a memo to this effect reminding staff of the new policy. Now, ” The alternative to this affect sounds plausible because affect and effect are pronounced almost identically in many accents, yet only one version aligns with conventional grammar rules. Think about it: misusing the phrase can undermine credibility, especially in formal contexts where precision is valued. Understanding the correct form not only improves writing quality but also sharpens overall language awareness.
Understanding the Core Difference: Affect vs. Effect
Before diving into the phrase itself, it helps to revisit the basic definitions of affect and effect.
| Term | Part of Speech | Primary Meaning | Typical Use |
|---|---|---|---|
| affect | Verb (mostly) | To influence or produce a change in something | The weather affects crop yields. |
| effect | Noun (mostly) | A result, outcome, or consequence | The new law had an immediate effect on traffic flow. |
| effect | Verb (less common) | To bring about or cause to happen | The manager effected sweeping reforms. |
| affect | Noun (psychology) | An observable expression of emotion | *The patient displayed flat affect. |
In everyday English, affect functions chiefly as a verb meaning “to influence,” while effect works as a noun meaning “the result of an influence.” The verb form of effect (“to bring about”) is rare and mostly appears in formal or technical writing. Because the two words sound alike, speakers often swap them unintentionally, leading to errors such as to this affect.
This is the bit that actually matters in practice.
The Correct Phrase: “To This Effect”
Meaning and Usage
To this effect is an idiomatic prepositional phrase that conveys “with this purpose” or “in order to achieve this result.” It signals that the speaker or writer is acting in line with a previously mentioned intention, statement, or goal. The phrase often follows a clause that outlines what is intended, and it introduces the action taken to fulfill that intention.
Examples:
- The committee issued a statement to this effect urging members to reduce waste.
- She sent an email to this effect confirming that the meeting would start at 9 a.m.
- The legislation was drafted to this effect to protect endangered habitats.
In each case, to this effect links the action (issuing a statement, sending an email, drafting legislation) to the purpose expressed earlier (urging waste reduction, confirming a meeting time, protecting habitats).
Grammatical Role
Structurally, to this effect functions as an adverbial phrase modifying the verb that precedes it. So * or *why? It answers the question how? the action was performed. Because effect here is a noun meaning “result” or “purpose,” the phrase parallels other constructions like to that end or for this purpose.
The Common Mistake: “To This Affect”
Why It Appears
The erroneous form to this affect arises primarily from phonetic similarity. In rapid speech, the final t of effect may be softened or dropped, making the two words sound nearly identical. Because of that, when writers rely on auditory memory rather than visual spelling, they may inadvertently write affect instead of effect. Additionally, because affect is a verb meaning “to influence,” some learners mistakenly think the phrase should convey “to influence this,” leading them to choose the verb form.
Why It Is Incorrect
Standard English dictionaries and style guides list to this effect as the established idiom. To this affect does not appear in reputable corpora (such as the Corpus of Contemporary American English or the British National Corpus) and is flagged as an error by grammar‑checking software. Using affect here creates a nonsensical construction: to influence this does not convey the intended meaning of acting in accordance with a purpose or result.
The official docs gloss over this. That's a mistake.
Incorrect example (to avoid):
- He posted a notice to this affect reminding residents of the curfew. (Incorrect)
Corrected version:
- He posted a notice to this effect reminding residents of the curfew. (Correct)
Persistence of the Confusion
Several factors keep the mistake alive:
- Homophony in Certain Accents – In rhotic accents where the final t is less pronounced, effect and affect can sound identical.
- Limited Exposure to the Idiom – The phrase to this effect is relatively formal; casual speakers may encounter it infrequently, reducing reinforcement of the correct spelling.
- Overreliance on Spell‑Check – While spell‑catchers flag affect vs. effect in many contexts, they sometimes miss the idiomatic nature of to this effect, allowing the error to slip through.
- Misapplication of Verb Logic – Learners who associate affect with action may think the phrase needs a verb, overlooking that effect here functions as a noun.
Awareness of these triggers helps writers guard against the mistake.
Practical Tips to Remember the Correct Form
Mnemonic Devices
- “Effect = End Result” – Both effect and end start with e. Think of to this effect as “to this end result.”
- “Affect = Action, Effect = End‑product” – Since the phrase describes achieving an end‑product (a purpose), choose the noun effect.
- Visual Cue – Imagine a checklist with a tick mark: ✔️ to this Effect (the “E” stands for “End”).
Self‑Checking Strategies
