In sociolinguistics, hypercorrection is the nonstandard use of language that results from the overapplication of a perceived rule of language-usage prescription. A speaker or writer who produces a hypercorrection generally believes through a misunderstanding of such rules that the form or phrase they use is more "correct", standard, or otherwise preferable, often combined with a desire to appear formal or educated.[1][2]
Linguistic hypercorrection occurs when a real or imagined grammatical rule is applied in an inappropriate context, so that an attempt to be "correct" leads to an incorrect result. It does not occur when a speaker follows "a natural speech instinct", according to Otto Jespersen and Robert J. Menner.[3]
Hypercorrection can be found among speakers of less prestigious language varieties who attempt to produce forms associated with high-prestige varieties, even in situations where speakers of those varieties would not. Some commentators call such production hyperurbanism.[4]
Hypercorrection can occur in many languages and wherever multiple languages or language varieties are in contact.
