The answer is "enumerated" powers.
The powers of the government that are particularly stated in the Constitution are some of the time called 'delegated' or 'expressed powers,' however frequently they are known as 'enumerated powers,' and they portray how a federal government with three branches can work successfully.
Congress can lay and gather taxes; it can coin cash, announce war, make rules for military lead, and raise and keep up armed forces and naval forces. These forces are genuinely obvious, and however there might be banter about the particulars of each authority, there's not a considerable measure of vagueness about the meaning of each.
