- I make the decisions as far as finance is concerned.
- Where spelling is concerned, he’s never been a strong student.
- There’s no reason to wait, as far as I’m concerned.
- So far as those big companies are concerned, we're just another little company that they can step on.
The first two sentences have been taken from the dictionary of Macmillan Publishers Limited, and the last two from Cambridge Dictionary. All these sentences have been used to explain the meanings of as far as something/someone is concerned. But in the second sentence only the word concerned has been used; as far as... has not been used. Please tell me why. Where as far as can be omitted?
Though these dictionaries explained the meanings of as far as something/someone before giving the examples stated above, I couldn't not understand it properly. It would be better if I got other alternative ways to rewrite above sentences. It would help me a lot. Please suggest the alternative ways to rewrite them.
