C is normally considered an extremely simple, lightweight language. I think the main lesson Forth has taught me is that we can design much simpler languages in the same space without sacrificing power and flexibility.
But perhaps at the expense of readability. Forth-like languages look quite elegant in small examples but C's more explicit syntax scales much better to larger code bases, IMO.
