Position of whatever

Question

Do not try in your home whatever you see here.

Is the sentence correct grammatically?Otherwise, how to use to speak such type of sentence?

Answer 1

There is nothing wrong with the syntax but the semantics are slightly unclear.

What if what you see is a box? It wouldn't make sense to try a box at home.

To make it clear that what you see is an action that's being performed, it would be better to add something more to the sentence:

Do not try in your home whatever you see being done here.

In this way, there can't be any confusion over seeing something that can't be done—simply because you are seeing somebody doing it.

There is nothing wrong with the use of whatever. But, having said that, the overall sentence might sound better if you reverse the components:

Whatever you see being done here, do not try it in your home.

However, that's just a matter of personal opinion. The original is fine—with the one changed I made.
