YES

Consider the TRS R consisting of the following rewrite rules:

	f(x,x) -> a
	f(g(x),y) -> f(x,y)

The TRS R is transformed (by dropping rewrite rules whose left-hand
sides contain a function symbol which does not occur in any right-hand
side) into a TRS R' which is empty. Hence R is terminating.
