a construction that expresses less common or 'disfavored' (see Section 2.4) combinations of information packaging and semantic content. Example: (Sam) is a barber is an instance of a nonprototypical predication construction: it expresses predication of an object category. This is not the most common or 'favored' type of predication; action predication is the prototypical predication construction. (Section 2.2.5)
