As To Why – Meaning & Correct Use Explained in Simple Terms
At its core, “as to why” connects two ideas:
- “as to” = about / regarding
- “why” = the reason something happens
Put together, “as to why” means “about the reason something happened.”
But here’s the catch.
You almost never need it.
Why? Because “why” already carries the full meaning on its own.
Simple example:
- ❌ I don’t know as to why she left early.
- ✅ I don’t know why she left early.
Same meaning. Fewer words. Better flow.
That’s the heart of As To Why – Meaning & Correct Use: it’s grammatically possible, but often unnecessary.
Why “As To Why” Feels Awkward in Real Writing
Let’s talk about why your brain trips over this phrase.
The structure stacks extra words onto something already complete:
- “as to” adds formality
- “why” already explains reason
So you end up with redundant layering.
Think of it like wearing two coats on a warm day. Technically fine. Practically uncomfortable.
Grammar breakdown
- “as to” → prepositional phrase
- “why” → interrogative adverb
When combined, they create a phrase that slows down the sentence without adding meaning.
What happens in real reading:
- Your reader pauses
- The sentence feels formal or legalistic
- The message loses natural flow
That’s why modern writing avoids it unless there’s a specific stylistic reason.
As To Why – Meaning & Correct Use in Formal Writing
Now here’s where things get interesting.
Even though the phrase is often unnecessary, it is not completely “wrong.”
You might still see it in:
- Legal documents
- Academic papers
- Formal reports
- Debate-style writing
Example in formal tone:
- There is disagreement as to why the system failed.
Here, the phrase slightly emphasizes discussion or uncertainty.
But even in formal writing, editors often prefer simpler versions:
- There is disagreement about why the system failed.
Key takeaway:
- It’s acceptable in formal contexts
- It is rarely the best choice

Common Mistakes with “As To Why”
Writers don’t usually break grammar rules here. Instead, they overuse the phrase in situations where it weakens clarity.
Let’s look at the biggest mistakes.
Overuse in everyday speech
People often say:
- ❌ I’m not sure as to why he did that.
This sounds overly formal and unnatural in conversation.
Better:
- ✅ I’m not sure why he did that.
Stacking unnecessary phrases
This happens more than you think.
- ❌ The reason as to why this happened is unclear.
This is double explanation.
You already said “reason.” You also said “why.”
Better:
- ✅ The reason is unclear.
- ✅ Why this happened is unclear.
Trying to sound more intelligent
Many writers think adding “as to” makes writing sound academic.
It doesn’t.
Instead, it often signals:
- Wordiness
- Lack of confidence in phrasing
- Outdated style
Clarity always wins over formality.
