Grammar Nazi

Grammar nazi/spelling nazi or grammar pedant/spelling pedant is a term for a pedant who compulsively criticizes or corrects others' grammar mistakes, typos, misspellings, and other errors in speech or writing.^[1] The term originated in 1990s discussion forums as a way to insult those who overly correct others' grammar. "Grammar Nazis" often correct mistakes humorously, though this can reinforce arbitrary standards of linguistic correctness. These corrections often reflect literacy privilege.^[2] The term is often criticized for being a lighthearted use of the word Nazi.^[3][4] Grammar nazis are often criticized themselves for being rude or harsh.^[5]

Grammar nazis can be helpful, but often go too far.^{[6][editorializing]}
