The Reason Of Why Usage Grammar And Is It Redundant

Language evolves, but so does our understanding of clarity, precision, and correctness. The phrase “the reason of why” has sparked debate among linguists, editors, and everyday speakers. Is it grammatically sound? Or is it redundant—repeating meaning unnecessarily? This question isn’t just about pedantry; it touches on how we communicate effectively in writing and speech. Understanding the nuances behind phrases like this one can sharpen your expression and prevent misunderstandings.

The core issue lies in the overlapping meanings of “reason” and “why.” Both point to causation. When used together, they risk doubling up on the same idea, potentially weakening the sentence. Yet, language isn’t always bound by strict logic. Idiomatic use, emphasis, and rhetorical effect often justify constructions that seem redundant at first glance. So, where does “the reason of why” stand in this balance?

Understanding the Components: Reason, Of, Why

To assess whether “the reason of why” is redundant, break down its parts:

• Reason: A cause, explanation, or justification for an action or event.
• Of: A preposition indicating possession, origin, or association.
• Why: An adverb or conjunction introducing a clause explaining cause or purpose.

When combined as “the reason of why,” the structure attempts to link a noun (reason) with a clause introduced by “why.” However, “reason” already implies causality. Adding “why” afterward often repeats that implication.

Consider this example: “The reason of why he left remains unclear.” Here, both “reason” and “why” refer to the cause of his departure. A tighter version would be: “The reason he left remains unclear” or simply “Why he left remains unclear.” Each version conveys the same idea without overlap.

Tip: If you can remove \"of why\" and the sentence still makes sense, it’s likely redundant.

Is “The Reason of Why” Grammatically Correct?

Strictly speaking, “the reason of why” is not grammatically incorrect in terms of syntax—it follows English word order and uses valid parts of speech. However, correctness doesn’t guarantee elegance or efficiency. In formal writing, conciseness is valued. Repeating ideas through multiple causal markers violates this principle.

Traditional grammar guides often label such constructions as pleonastic—using more words than necessary. For instance, Fowler’s *Modern English Usage* criticizes redundancy in expressions like “each and every” or “free gift,” advocating for leaner alternatives. By that standard, “the reason of why” falls into the same category.

That said, natural speech often embraces redundancy for emphasis or rhythm. People say things like “I saw it with my own eyes” instead of “I saw it,” even though “own” adds no new information. Similarly, “the reason of why” may persist in spoken English because it feels more complete or emphatic to some speakers.

“Redundancy isn’t always wrong. Sometimes it’s rhetorical. But in professional writing, precision should win over habit.” — Dr. Lydia Chen, Linguistics Professor, University of Toronto

Common Alternatives and Best Practices

Writers aiming for clarity and polish have several stronger options:

1. Use “the reason” + that/infininitive: “The reason he resigned was stress.”
2. Use “why” alone: “Why he resigned remains unclear.”
3. Reword entirely: “He resigned due to stress” or “Stress led to his resignation.”

Avoiding “of why” after “reason” aligns with editorial standards in journalism, academic writing, and business communication. Style guides from *The Chicago Manual of Style* to *AP Stylebook* recommend concise phrasing and discourage unnecessary wordiness.

Construction	Recommended?	Comment
The reason he failed was poor preparation.	Yes	Clear and concise.
Why he failed was poor preparation.	Yes	Slightly more conversational but acceptable.
The reason of why he failed was poor preparation.	No	Redundant; avoid in formal writing.
The reason for his failure was poor preparation.	Yes	Perfectly correct and widely accepted.
He failed because of poor preparation.	Yes	Direct and active voice.

Real Example: Redundancy in Public Communication

In 2020, a press release from a regional nonprofit stated: “The reason of why enrollment dropped is currently under review.” Internal editors flagged the phrase during proofreading. After revision, the sentence read: “The reason enrollment dropped is under review.”

Feedback from stakeholders indicated the revised version sounded more confident and professional. One board member noted, “It felt like we were hiding behind words before. Now it’s direct.” This case illustrates how small grammatical choices impact perception. Even if listeners don’t consciously notice “the reason of why,” the cumulative effect of wordy phrasing can dilute authority.

Step-by-Step Guide to Eliminating Redundant Phrases

Follow these steps to audit your writing for similar redundancies:

1. Identify key nouns related to cause: Look for words like “reason,” “cause,” “purpose,” “basis.”
2. Check what follows them: Are they paired with “why,” “because,” or “of which”? These may signal overlap.
3. Test removal: Delete “of why” and see if the sentence retains meaning.
4. Replace if needed: Use “that,” rephrase with “because,” or simplify the entire clause.
5. Read aloud: Clunky or repetitive phrasing often becomes obvious when spoken.

Tip: Use search functions in word processors to find “reason why” or “reason of why” in your drafts. Review each instance critically.

Expert Insight on Linguistic Evolution

While prescriptive grammar discourages “the reason of why,” descriptive linguists acknowledge its presence in real-world usage. Language isn’t static, and what seems redundant today might become normalized tomorrow.

“People aren’t using ‘the reason of why’ by accident. It serves a rhythmic or emphatic function. But in edited writing, we prioritize clarity over comfort.” — Prof. Marcus Reed, Sociolinguist, Stanford University

This duality reflects a broader tension in English: rules versus usage. While “the reason of why” appears in casual conversation and informal texts, it rarely survives rigorous editing. Its survival in speech doesn’t grant it automatic legitimacy in formal contexts.

Frequently Asked Questions

Is “the reason why” always wrong?

No, “the reason why” is widely used and generally accepted, though some purists prefer “the reason that” or simply omit “why.” For example, “The reason why I called” is common in speech and increasingly tolerated in writing. However, “the reason of why” goes a step further and is less defensible due to the added preposition “of.”

Can redundancy ever be useful?

Yes. In rhetoric, repetition can emphasize key points. Phrases like “each and every” or “first and foremost” are technically redundant but serve stylistic purposes. The key is intentionality. Unconscious redundancy weakens writing; deliberate repetition strengthens it.

Are there other similar redundant phrases to avoid?

Absolutely. Common examples include:

• “Return back” – “return” already means “go back.”
• “Advance warning” – all warnings are by definition advance.
• “End result” – the word “result” implies an end.
• “Personal opinion” – opinions are inherently personal.

Editing out such phrases tightens your prose and enhances professionalism.

Final Thoughts: Precision Over Habit

Language shapes thought. The way we construct sentences influences how clearly we convey ideas. While “the reason of why” may slip into conversation naturally, it deserves scrutiny in written form. Redundancy, especially unintentional, obscures meaning rather than clarifying it.

Choosing precision doesn’t mean rejecting natural speech patterns. It means being mindful of context. In emails, reports, essays, and publications, lean language commands attention and respect. You don’t need extra words to make a point—you need the right ones.

Next time you write “the reason of why,” pause. Ask yourself: Am I adding value, or just filling space? Then revise with confidence.
