In the English language, there are grammatical constructions that many native speakers use unquestioningly yet certain writers call incorrect. Differences of usage or opinion may stem from differences between formal and informal speech and other matters of register, differences among dialects (whether regional, class-based, or other), and so forth. Disputes may arise when style guides disagree with each other, or when a guideline or judgement is confronted by large amounts of conflicting evidence or has its rationale challenged.
Some of the sources that consider some of the following examples incorrect consider the same examples to be acceptable in dialects other than Standard English or in an informal register; others consider certain constructions to be incorrect in any variety of English. On the other hand, many or all of the following examples are considered correct by some sources.
Generic you – e.g., "Brushing your teeth is a good habit" as opposed to "Brushing one's teeth is a good habit"
Singular they - e.g., "No man goes to battle to be killed. But they do get killed"
Flat adverbs – e.g., "Drive safe" as opposed to "Drive safely"
Using "I" vs. "me" in the oblique case, e.g., "He gave the ball to Bob and I" instead of "He gave the ball to Bob and me". This is often called a hypercorrection, since it is perceived as related to avoidance of the stigmatized incorrect use of the oblique form. See Between you and I.
The validity of aren't as a negative first-person singular conjunction for to be in interrogative uses – e.g., "Aren't I the one you were talking about?"
Ending a sentence with a preposition – e.g., "You have nothing to be afraid of" (vs. "You have nothing of which to be afraid") – criticized by grammarians in the 1600s by analogy with Latin grammar and by some teachers since, though many have always accepted it as part of standard English
Conflating the past and past participle forms of the verb - e.g. "I should have went" and "I done that yesterday".
Order of quoted punctuation marks, i.e., American style ("Many dreams were characterized as 'raw,' 'powerful,' and 'evocative'") vs. British style ('Many dreams were characterized as "raw", "powerful", and "evocative"'). Some American authorities (such as the APA and CMS) require the former, while others (such as the LSA) allow, prefer, or require the latter.
Gender-specific and gender-neutral pronouns – Replacing masculine pronouns where they are meant to refer to a person of either gender with both masculine and feminine pronouns, alternative phrasing, or grammatically controversial gender-neutral personal pronouns such as the singular they or newly invented words like "hir" and "ze"
Terms for humans in general – Replacing nouns like "mankind" with "humankind"
The following circumstances may feature in disputes:
Myths and superstitions
There are a number of alleged "rules" of unclear origin that have no rational basis or are based on things such as misremembered rules taught in school. They are sometimes described by authorities as "superstitions" or "myths". These include "rules" such as not beginning sentences with "and":69 or "because":125–6 or not ending them with prepositions.:617 See common English usage misconceptions.
No central authority
Unlike some languages, such as French (which has the Académie française), English has no single authoritative governing academy, so assessments of correctness are made by "self-appointed authorities who, reflecting varying judgments of acceptability and appropriateness, often disagree".:14
While some variations in the use of language correlate with age, sex, ethnic group, or region, others may be taught in schools and be preferred in the context of interaction with strangers. These forms may also gain prestige as the standard language of professionals, politicians, etc., and be called "standard English", whereas forms associated with less educated speakers may be called "nonstandard" (or less commonly "substandard") English.:18
Because of the stigma attached to violating prescriptivist norms, some speakers – attempting to avoid mistakes – may incorrectly extend the rules beyond their scope.:14
Use by widely respected authors may lend credibility to a particular construction: for instance, Ernest Hemingway is known for beginning sentences with And.
Prescriptivist arguments about the correctness of various English constructions have sometimes been based on Latin grammar.:9
Analogy with other constructions
It is sometimes argued that a certain use is more logical than another, or that it is more consistent with other usages, based on analogy with different grammatical constructions. For instance, it may be argued that the accusative form must be used for the components of a coordinate construction where it would be used for a single pronoun.:9
Speakers and writers frequently do not consider it necessary to justify their positions on a particular usage, taking its correctness or incorrectness for granted. In some cases, people believe an expression to be incorrect partly because they also falsely believe it to be newer than it really is.
It is often said that the difference between prescriptivist and descriptivist approaches is that the former prescribes how English should be spoken and written and the latter describes how English is spoken and written, but this is an oversimplification.:5 Prescriptivist works may contain claims about the incorrectness of various common English constructions, but they also deal with topics other than grammar, such as style.:6 Prescriptivists and descriptivists differ in that, when presented with evidence that purported rules disagree with most native speakers' actual usage, the prescriptivist may declare that those speakers are wrong, whereas the descriptivist will assume that the usage of the overwhelming majority of native speakers defines the language, and that the prescriptivist has an idiosyncratic view of correct usage.:7–8 Particularly in older prescriptivist works, recommendations may be based on personal taste, confusion between informality and ungrammaticality,:6 or arguments related to other languages, such as Latin.:9
In contrast to their generally high level of tolerance for the dialects of other English-speaking countries, speakers often express disdain for features of certain regional or ethnic dialects, such as Southern American English's use of y'all, Geordies' use of "yous" as the second person plural personal pronoun, and nonstandard forms of "to be" such as "The old dock bes under water most of the year" (Newfoundland English) or "That dock be under water every other week" (African-American Vernacular English).
Such disdain may not be restricted to points of grammar; speakers often criticize regional accents and vocabulary as well. Arguments related to regional dialects must center on questions of what constitutes Standard English. For example, since fairly divergent dialects from many countries are widely accepted as Standard English, it is not always clear why certain regional dialects, which may be very similar to their standard counterparts, are not.
Different constructions are acceptable in different registers of English. For example, a given construction will often be seen as too formal or too informal for a situation.
^ lists "one; anyone; people in general" as a definition without qualification that it is non-standard
^ requires replacing "you" with another word unless it means "you the reader".
