"According to" is used to introduce the source of a fact or opinion. For example:
"According to the BBC weather forecast, it is likely to rain tomorrow in East London."
Below is a grammatically correct but strange use of "according to":
"According to me, West Ham United is the best football team in England."
Clearly, supporters of other teams will not agree! But it is my opinion and I have the right to it. However, the use of "according to me" always sounds strange. To explain why, this would be a possible response:
"According to you, eh? Have you suddenly become an expert on football then? Perhaps you should get a job as a football commentator!"
This is an ironic response which suggests that the speaker was a little arrogant, and that he takes his own opinion a bit too seriously.
So, "according to" is good with any source except yourself ("me"). Can anyone think of some common alternatives to use in speech and/or writing?
Thanks again for the comments.
EG = "as far as I am concerned" often introduces a rebuttal or firm conclusion. If we continue my story, an Arsenal supporter might say:
"As far as I am concerned, there is absolutely no evidence to suggest that West Ham are the best football team at the moment."
Sudeep: don't worry about it too much. In my experience, native speakers just don't say "according to me", for the reasons I mentioned.
"as per my knowledge is concern" is not right. But these are good suggestions from Sudeep:
"In my view", and
"As far as I know" (not "so")
