Is it true that Counterterms are added in quantum field theory to cancel out divergences and renormalize physical parameters?

Counterterms are standard theoretical constructs introduced in perturbative quantum field theory to absorb ultraviolet divergences and yield finite, physical parameters. No citation is needed for this textbook definition.

The analysis

The claim states a foundational definition and textbook fact of quantum field theory: counterterms are added to cancel divergences and renormalize parameters. This is a matter of common knowledge and standard formalism in physics, making formal citation unnecessary.
