n
The process in quantum field theory of redefining parameters (like mass and charge) to remove infinities from calculations and produce finite, physically meaningful results.
n
(broadly) Any mathematical procedure that systematically removes infinities or singularities from a theory by redefining its variables.

Etymology
The term is a modern scientific compound built from classical elements. The core concept, "normal," originates from the Latin norma, a carpenter's square used to ensure right angles, which evolved to mean any authoritative standard or pattern. The prefix "re-" signifies a repeated action, implying a return to or a renewed establishment of a standard. The suffix "-ization" denotes the process of making or causing. Thus, the literal morphemic logic is "the process of making standard again." In its specific physics context, this describes the technical procedure of repeatedly adjusting the parameters of a quantum theory to eliminate meaningless infinite results, thereby restoring a finite, "standard," and predictive mathematical framework.
Analysis
Structure: re (again) + normal (standard) + ization (process of making)
re: Latin prefix meaning "again, back".
normal: From Latin normalis (made according to a carpenter's square, standard), from norma (carpenter's square, rule, pattern).
ization: A compound suffix formed from -ize (verb-forming suffix from Greek -izein) + -ation (noun-forming suffix from Latin -ationem, indicating an action or process).
Examples
Renormalization is a crucial technique for making sense of quantum electrodynamics.
The physicist explained how renormalization allows for incredibly accurate predictions.
The mathematical process of renormalization removed the troublesome infinities from the equation.
