What is Attraction (grammar)?

Attraction, in linguistics, is a type of error in language production that incorrectly extends a feature from one word in a sentence to another. This can refer to agreement attraction, wherein a feature is assigned based on agreement with another word. This tends to happen in English with Subject Verb Agreement, especially where the subject is separated from the verb in a complex noun phrase structure. It can also refer to Case Attraction, which assigns features based on grammatical roles, or in dialectal forms of English, Negative Attraction which extends negation particles.
