Forms: see re- prefix and normalization n.

Origin: Formed within English, by derivation. Etymons: re- prefix, normalization n.

Etymology: < re- prefix + normalization n. Compare later renormalize v.

1. The process of making or becoming normal again; renewed normalization. Also: an instance of this.

1908 Amer. Jrnl. Psychol. 19 211 The chance of man's renormalization from the fall is perhaps about as grave as all religions make it.

1957 W. Frank Bridgehead vii. 128 In Herzl, the bare will of Zionism as a practicable renormalization of the Jew is nakedly present.

1990 Sydney Morning Herald (Nexis) 26 Jan. 7 The most important implication of the vote is to slow down the process of ‘renormalisation’ which officials have been pursuing.

2001 J. McPhee Center of Things viii. 150 Being with Marco, as frustrating and annoying as he could be, she often felt herself undergo a kind of renormalization process.

2. Physics. The process of making a mathematical representation more tractable by redefining a variable; spec. a mathematical procedure in quantum mechanics by which unwanted infinities are removed from the solutions of equations by redefining parameters such as the mass and charge of subatomic particles.
