I want to qualify the word 'money' using the words good, decent, etc. But I am not sure how to use them. Do I have to say a good amount of money or a decent amount of money? Or just good money or decent money? Can I use good and decent interchangeably?
Good money and decent money (often used after It's...) are both frequently used to say that a job / appointment / opportunity / task is well paid.
Other common adjectives in this context are ample / adequate / abundant
People also talk about lots / loads / tons of money, as well as easy money and many more.
The source below gives lots of alternatives.
