A mistake from my part

[Talab1234]

“It was a mistake from my part.”

Is this a correct sentence?

 

[emsr2d2]

No.

It was a mistake on my part.

I agree with emsr2d2 of course but we don't have context. Very often, a more natural sentence would be 'I made a mistake".

 

[emsr2d2]

There are plenty of contexts in which it would work, though. If the OP wants to use that sentence, they can, but not with "from". I agree that "I made a mistake" is more common.
