Here we have a subject term (the names ‘Bill’ and ‘Tony’, and the demonstrative ‘this’), and things are said of what they pick out: ‘is rich’, ‘grins’, or ‘is an orange’. These terms stand for conditions that things might meet. They are called ‘predicates’: the rich things satisfy the predicate ‘is rich’, and other things do not. This is the basic subject-predicate form of information.
