Surrey Defectiveness Database


The term 'defectiveness' refers to gaps in inflectional paradigms — specifically, gaps which do not appear to follow from natural restrictions imposed by meaning or function. The Typological Database on Defectiveness illustrates different types of defective paradigm according to various morphological and morphosyntactic parameters. The Cross-linguistic Database on Defectiveness looks at the prevalence of inflectional defectiveness in a controlled sample of genetically and geographically diverse language.

The Surrey Typological Database on Defectiveness illustrates different types of defective paradigm according to various morphological and morphosyntactic parameters in a sample of 27 languages.

About the database

This database illustrates different types of defective paradigm according to various morphological and morphosyntactic parameters:

  • Word class: what word class do the defective lexemes belong to?
  • Morphosyntactic category: what morphosyntactic features characterize the missing forms?
  • Paradigmatic correlation: can the gap(s) in the paradigm be described in terms  of an easily definable morphological category (e.g. a word missing a particular morphological stem) or a morphosyntactic category (e.g. a verb missing its past  tense or 1st person singular)?
