(slang, idiomatic, potentially, _, offensive, humorous, see usage note at Nazi) A person who habitually criticizes the grammar and (often) usage in others' speech or writing, often in ways that are sometimes not even linguistically accurate.

He had to explain that the grammar Nazi's tantrum was mistaken because interposing an adverb to fall between the components of a to-infinitive is usually not wrong in English grammar.
Origin: First use appears c. 1991. From. Origin information sourced from Wiktionary contributors (CC BY-SA 4.0).
