Description

(By Jeremy Collins and Jay Latarche): "Do property words used as predicates take on verbal morphology? The predicative property word need not take exactly all verbal marking. If there is at least some marking that verbs and predicative property words share, this counts as 1 (for example, if a language has he runs and he greens). However, if there is additional morphology or there are additional elements that the property word requires, then this feature should be coded as 0. This should apply to most property words in the language. Property words semantically roughly correspond to adjectives in those languages that have a separate adjective word class. We want to include elements that mark ‘adjectival’ function but that might not be described as ‘adjectives’."
