is "ich kann fur euch nicht bezalen" correct too? Is there a rule for where one should write "nicht"?
It depends on what you negate. if you place the nicht in fron of "für euch", you just negate that you can't pay for them. If you place it like you did you negate the verb/ the whole statement, so it sounds more like you can't pay at all.
a two years later thank you very much to both Trage und Antwort :) sehr nùtzlich
Is 'fuer' necessary here? BEOLINGUS dictionary gives the example 'die Waren bezahlen= to pay for goods,
Ich kann nicht für euch bezahlen = I can't pay the entry fee (or whetever) for you, you have to pay for yourselves.
Ich kann euch nicht bezahlen = either: I can't pay the money I owe you or: I can't pay the price that someone demands from me if I want to buy you
Thanks for the explanation. BTW is there a difference between bezahlen and zahlen?
Yes, but it often overlaps. zahlen just means you give out money, while bezahlen means you give out money in exchange to something, like to settle a bill or debt. So if your dad just regularly gives you money for your expenses without demanding a return, you use "zahlen". If you put money into your savings account, you use (ein)zahlen. For most other things, you can use both, although you prefer bezahlen when you include the object you are paying for in the sentence:
in the restaurant: "Ich möchte zahlen!" (I want to pay!)
or "Ich möchte die Rechnung bezahlen" (I want to pay the bill!)
