Contrastive focus reduplication,[1] also called contrastive reduplication,[1] identical constituent compounding,[2][3] lexical cloning,[4][5] or the double construction, is a type of syntactic reduplication found in some languages. Doubling a word or phrase – such as "do you like-like him?" – can indicate that the prototypical meaning of the repeated word or phrase is intended.[1]
"As a rough approximation, we can say that the reduplicated modifier singles out a member or subset of the extension of the noun that represents a true, real, default, or prototype instance."[5]
In English, the first part of the reduplicant bears contrastive intonational stress.
Contrastive focus reduplication in English can apply not only to words but also to multi-word phrases such as idioms, or to word stems without their inflectional morphemes.
