    'by' and 'for'

    You can substitute 'a' by/for 'b'.

    Hi,
    What's the correct preposition, please? Is there any rule for it?
    Thanks.

    substitute 'a' for 'b'
    This means you use 'a' (in the place)(instead) of 'b'.

    Re: 'by' and 'for'

    thanks a lot, 2006.
    I had betted on 'by' and lost my money.
    I wonder when to use 'by' and 'for'. is there a rule, please?
    if I was talking about people, was it right to say 'substitute John for Mary'?
    also, would it be correct to say 'to exchange dollars for euros'?
    thanks again.

    This is a big topic.
    We just say "substitute for", not 'substitute by'.
    You could say, You can change it by replacing 'b' with 'a'.

    Thanks a lot.

    I have 2 questions please:


    1) if the verb was ' to replace', which proposition (by/for) should I use, please?

    2) I am confused about the past of 'to bet'. My Oxford dictionary says that 'betted' is correct:

    bet
    verb (bets, betting; past and past participle bet or betted)

    I wonder if both are really possible but 'betted' is rarely used.


    Thanks again.

    there are two basketball players named bad and good.

    good will replace bad.. (no preposition)
    bad (will be)(was) replaced by good.
    the coach will replace bad with good.
    we need a repacement for bad.

    only "bet" is used where i am. Maybe "betted" is used elsewhere.

    thanks again.
