Does "what little action occurs" make sense? It seems wrong grammar-wise. Maybe just "what little action" might be correct, but "repeat what little action occurs" is a crossed structure of "repeat what"+"what action occurs", so it sounds weird.
Can you tell me if it makes sense and what is the grammar term for "what" in this case?
ex)...The play(waiting for Godot) has two acts. The second act repeats what little action occurs in the first, but with a few changes : the tree, for instance, gains one leaf...
There isn't much action. There is little action. That little bit of action is repeated. What little action there is = all the action, even though there is very little of it.
We don't have much milk left, but add what little there is to the muffin mix, please.
I don't have much money, but you are welcome to what little there is. What little there is should prove to be enough.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
