What is the nature of the term 什么都? While talking on discord someone typed that they were studying, to which I jokingly replied,  &quot;我已经学会什么都了，没有没学的&quot;, though people were quick to correct me, apparently 什么都 is not a noun and belongs before the verb. I don't like this one bit, 什么都 to me seems like the object of the verb and I can't make sense of it as an adverb. I thought maybe historically 什么都 was preceded by a verb that has since fallen out of fashion, making the sentence originally function as a serial verb construction (我已经_什么都学会了) which makes intuitive sense to me but is pure conjecture. Whatever the case is, I would like someone to clear up my confusion
This might help you to understand it better.
我已经(把)什么都学会了.
And 我已经什么都学会了 just omits 把.
Another example: 我把这本书读完了. Colloquially, you can say 我这本书读完了.
More: 我把话说完了/我话说完了。
But the omission doesn't always work well.  E. g.  我把这件事给忘了.  It doesn't sound right to say 我这件事给忘了.  In this case, we do need 把 and can't be omitted.
So be cautious of this omission in practice.
