I really want to buy that house on the corner.
Well, Why don’t you save money then instead of spending it all on expensive clothes?
We use “save money” when we want to stop spending so much money and want to buy something that we usually can’t afford like a house or a car. We use “save” when we want to keep something or gather something together.
“Safe Money” is possible in English but is unlikely to be used very often. “Safe Money” could be used to mean money that is stored in a “safe” or money that is not in danger.
