Why we avoid the ‘Multiple Inheritance’ issue in Usage-based Cognitive Construction Grammar

This squib revisits the phenomenon of ‘Multiple Inheritance’ (MI) and discusses reasons why many usage-based, cognitive construction grammarians seem to be avoiding it when modeling the constructicon and linguistic knowledge. After a brief discussion of the concept and some examples from the literature, the paper examines potential reasons for the apparent disinterest. Finally, the author points to some open questions regarding MI by discussing a specific example, namely modified NPN constructions like day after hellish day or hour after hour of dominoes. It can be argued that these strings inherit their characteristic features from several different abstract templates.
