The phrases “as evidenced by” and “as evident by” look very similar, but they are not equally standard in English. This small difference can cause confusion, especially in academic, professional and formal writing. If you are trying to explain that something is clearly shown or supported by evidence, choosing the right expression makes your sentence more natural and grammatically sound.
The standard and widely accepted expression is “as evidenced by.” It means that something is demonstrated, supported or made clear by a particular fact, example, result, or piece of evidence. “As evident by” is sometimes used but it is generally considered less standard and less natural than “as evidenced by.” In most formal writing, “as evidenced by” is the safer choice.
Quick Answer
“As evidenced by” is the standard and preferred expression. It means “as shown or demonstrated by.” “As evident by” is sometimes heard or written, but it is generally less idiomatic. For academic, professional and formal writing, use “as evidenced by.”
Why Do People Confuse “As Evidenced By” and “As Evident By”?
The confusion comes from the similarity between evidenced and evident.
Both words are related to the idea of evidence, but they have different grammatical roles.
- Evidenced is the past participle of the verb evidence.
- Evident is an adjective meaning clear, obvious, or easy to see.
The expression “as evidenced by” uses the verb evidence in a passive construction.
For example:
His commitment is evidenced by his consistent effort.
The phrase means that his commitment is demonstrated by his effort.
By contrast, evident is normally followed by in, from or to, depending on the sentence.
His commitment is evident in his consistent effort.
This is why “as evident by” is generally not the preferred construction.
As Evidenced By
“As evidenced by” is the standard expression.
It means:
as shown by
as demonstrated by
as supported by
It is particularly common in formal, academic, business, legal and analytical writing.
Examples
- She is highly experienced, as evidenced by her impressive portfolio.
- The company is growing rapidly, as evidenced by its increasing sales.
- His dedication is clear, as evidenced by his years of service.
- The results show improvement, as evidenced by the latest test scores.
In each example, the information after “as evidenced by” provides evidence supporting the statement.
As Evident By
“As evident by” is sometimes used to mean the same thing as “as evidenced by,” but it is generally less standard and less idiomatic.
For formal writing, it is better to avoid it.
Instead of:
The improvement is as evident by the results.
Use:
The improvement is as evidenced by the results.
Or, depending on the sentence:
The improvement is evident from the results.
The second alternative is especially useful because evident is an adjective.
