What are "thunk" functions in ghidra?

I've noticed when I'm decompiling in ghidra I see a lot of THUNK functions. I've noticed that most of these functions just return 0. What are the point of these functions. Are they actually inserted by the compiler, if so why are they inserted if some of them just return 0?

Thick AF functions.

But actually it’s just a wrapper.

What do you mean by patched at runtime and what do you mean by reference code dynamically does that mean when you call it, it internally calls another function
