Do you know this word “stuff”?? As a noun, it is uncountable (数えられない), but very common to describe 物 or 事 in English.
- There is a lot of stuff in my wife’s bag.
- I have some stuff to do today.
- I gave some of my stuff to my brother.
- She learned interesting stuff at the seminar.
- Can you help me move my stuff tomorrow? (引越し)
- My father knows a lot of stuff.
Also, you could use “things” instead of “stuff” for the same meaning. The only real difference is that “thing” is a 数えられる名詞, so you need to mind your grammar.
- There are a lot of things in my wife’s bag.
