PRIMITIVE
topic–comment (a.k.a. categorical) (INF/CXN) = the information packaging in which one concept (the comment) is predicated about another concept which is referred to (the topic); and the construction that expresses that information packaging. Example: The bus stopped is an instance of a topic–comment construction in which stopped is the comment and The bus is the topic. Topic–comment information pack- aging is basically synonymous with predication; the term ‘topic–comment’ high- lights the fact that a predication is a predication about a referent.
