(By Hannah J. Haynie): "This feature focuses on standard negation, or the construction(s) that mark negation of (at least) dynamic (i.e. non-stative) verbal predicates in declarative mood. It is possible that the same negation construction will be used for other purposes as well (e.g. with stative or non-verbal predicates), but clauses involving predicates other than the aforementioned dynamic verbal predicates in declarative mood should be disregarded. ❡
The position ‘clause-initial’ includes prefixes on clause-initial verbs, even if the negator is not the left-most prefix, but suffixes on clause-initial verbs do not count as clause-initial negation. If the negator consists of two obligatory elements and only one is clause-initial, this is sufficient to count as clause-initial negation and to trigger a 1 for this feature. As with other word order features in this dataset, we are concerned with the order of the negative marker when the clause has its canonical intransitive or transitive word order. We are not interested in cases of argument omission or pragmatically marked constructions (e.g. focus); these should be disregarded in coding this feature."
Instead of "canonical order", the Grammaticon has "dominant order".
