A standard negation construction is a clausal construction with a negated verbal predicate in a declarative non-subordinate clause.
"Standard negation" is a typical typological concept that will hardly be needed in language description.
"Since Payne (1985) and especially Miestamo (2025), typologists have used the terms 'standard' and 'non-standard' negation. 'Stanard negation' is the non-emphatic negation of a lexical main verb in a declarative main clause... Negation in all other functions is collectively referred to as 'non-standard negation'..."
