Suppose your child is about to untie the bow on his shirt & you say "leave it as it is".
is it idiomatic to say "leave it as it is" when you want someone not to alter the current structure of something?
Also, are "leave it what it is" or "leave it where it is" idiomatic?
Note: when I googled "define: 'leave it as it is'", it showed no definition, but just 1 forum. I am not sure I can trust the definition in the forum.
