Heine & Kuteva (2005) proposed the concept of a grammaticalization area. Given the recent appearance of the concept of constructionalization, (Traugott & Trousdale, 2013) it seems reasonable to ask whether there are constructionalization areas as well. The paper exemplifies this concept with the help of the Tungusic language Manchu and some surrounding lan- guages. Manchu does not have the common Tungusic negative verb e‐, but, like Mongolian, employs the negative existential akū instead (e.g., Ikegami, 1999 ). Manchu and Mongolian share not only this development, but also an underlying interlingual constructional network (Höder, 2012). The paper proposes the name areal construction grammar as a label for those aspects of construction grammar that are concerned with the study of lan- guage contact.
