This list comprises widespread modern beliefs about English language usage that are documented by a reliable source to be misconceptions. With no authoritative language academy, guidance on English language usage can come from many sources. This can create problems, as described by Reginald Close: Teachers and textbook writers often invent rules which their students and readers repeat and perpetuate. These rules are usually statements about English usage which the authors imagine to be, as a rule, true. But statements of this kind are extremely difficult to formulate both simply and accurately. They are rarely altogether true; often only partially true; sometimes contradicted by usage itself. Sometimes the contrary to them is also true. Perceived violations of correct English usage elicit visceral reactions in many people. For example, respondents to a 1986 BBC poll were asked to submit "the three points of grammatical usage they most disliked". Participants stated that their noted points "'made their blood boil', 'gave a pain to their ear', 'made them shudder', and 'appalled' them". Despite this, not all commonly held usage violations are nonstandard forms or errors; many are only perceived as such. (en)
