In my review queue, I received a nice answer and I suggested adding some reference. A few minutes later the answerer asked what kind of reference needed.
I received that response and redirected to the post. And then I discovered another answer in the post has already provided the reference. So, I replied
... I came here again because of the INBOX message. And then I found another answer has given a link. So, just ignore it...
I guess my response is grammatical.
per Cambridge Dictionary, "find" means "to discover where a thing is unexpectedly". It is the situation, I didn't expected there has already been a reference in that post. "Discover" is used in the definition, so I guess I could substitute "discovered" for "found".
... I discovered another answer has given a link ...
So, "found" and "discovered" are interchangeable in this context, is my understanding? Could someone please give a hint? Thanks in advance.
