I have this sentence:

Group theory is one of my favourite areas in mathematics, as evidenced by the fact that I chose to do two group theory modules in my undergraduate course.

I am wondering if it should be evident instead of evidenced.

  • 'As is evidenced by' is the fuller version. Less rarefied are 'as shown by' / 'as is shown by'. 'As demonstrated by' works in a scientific register. // Possibly even starchier are 'as exemplified by' etc and 'as epitomized by' etc. And as for 'as evinced by'.... May 29 '19 at 18:06

I believe the expressions should be "as evidenced by" and "as is evident from," respectively.

My preference, however, would be to opt for neither expression. Instead, I normally use "as demonstrated by." It's identical in meaning to the phrase you're trying to use, and there is little chance of either confusion or misuse, as is possible with the other expressions.


My first thought was that as evidenced by is a "malapropism". But as evinced by this chart...

A Google ngram chart showing high usage of "as evidenced by" against a very low utilization of "as evinced by" with near concurrent usage until 1860 (0.0000200%) at which time "as evidenced by" grew greatly and "as evinced by" declined to minimal usage.

...I'm slightly out of touch with current usage.

However, I do still think as evident by is a latter-day malapropism - as shown by this chart, where usage falls far short of even as evinced by.

    Evidence can be a verb; whether it is too archaic to use is a personal view. Evident cannot be, so as evident by is wrong, possibly an eggcorn. Dec 23 '13 at 19:10

    One could use as made evident by perfectly grammatically (although it's not in nearly as common usage).

In health care reports, it is always "as evidenced by".
