Part of speech: noun

Definitions

1. The procedure of modifying values or parameters in a system to return it to a standard or normalized scale

Etymology: "Renormalization" is a plain compound built from two parts. The prefix "re-" means "again" or "back," and it comes from Latin "re-" through Old French and Middle English, and it traces further back to a Proto-Italic root. The second part, "normalization," is a noun formed from "normal" with the suffix "-ation," and that is what the prefix attaches to. Taken together, the word describes returning something to a standard state after it has drifted away from it. The "re-" does the work of "again": the system is normal, it is disturbed, and renormalization brings it back to that normal condition.
