Governments have spent quite a lot for space exploration using public money.
Indonesian collocation? (Let me know if I’m wrong in the comments below..)
Spend money (on someone/something)
The preposition you need in English is spend on:
- Governments have spent quite a lot on space exploration using public money.
Spend money (doing something)
Another way to express this is using __ing:
- Governments have spent quite a lot of public money exploring space.
Spend money (somewhere)
You can also spend money in a particular place:
- Governments have spent quite a lot of public money in developing countries.
In this case, of course other prepositions of place will be possible (around, at, etc.)
The language used to talk about spending money also applies to spending time, except that we don’t often spend time ‘on‘ someone, rather we spend time ‘with‘ them:
- Last weekend I spent some time with my girlfriend. We spent Saturday evening at the cinema and after that we spent some time walking along the beach. She noticed that I had gained weight and urged me to spend more time on physical exercise.
Spending time is also discussed in a previous post.
