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.
