I am writing to the following sentence written by a native speaker:
... and build a corpus with of effective tests, reports, analyses and evaluation results.
What's really confusing me is the usage of with of
. Isn't it more understandable, to just do this?
... and build a corpus with effective tests, reports, analyses and evaluation results.
Why do we need to use with of
? And I searched it in Google and it only finds one usage. I didn't even know if it is grammatically correct.
