(By Johan van der Auwera and Ludo Lejeune with Umarani Pappuswamy and Valentin Goussev): "This map shows to what extent languages have second person singular and plural imperatives as dedicated morphological categories... The first type shown on the map includes languages that have special morphological marking both for the imperative second singular and for the imperative second plural... The second type shown is that of languages that possess morphologically specialized imperative forms for the second singular but not for the second plural... The third type shows languages with dedicated morphology for the second plural imperative, but not for the second singular imperative... Languages of the fourth type have a specialized second person imperative that does not distinguish between singular and plural... The final type shows languages that have no morphologically dedicated second person imperative at all, neither for the singular nor for the plural..."
