Surrey Deponency Databases

Deponency describes mismatches between morphology and morphosyntax. A mismatch occurs where the word form is used in some function incompatible with its normal function. The Typological Database on Deponency records the logical space of deponency: What features may be affected, and what are the characteristics of the resulting paradigm? The Cross-linguistic Database on Deponency looks at the presence of morphological mismatches in a controlled sample of genetically and geographically diverse languages.

The Surrey Cross-linguistic Database on Deponency provides an impression of the prevalence of deponency in the languages of the world using a stratified sample of 100 languages.
