  Complex demonstratives are expressions of the form that \(N\) or this \(N\), where \(N\) is a common noun phrase. Examples include ‘this man’, ‘that red car’, and ‘that woman who is wearing a blue coat’. One major question about complex demonstratives is whether they are singular terms or quantifier phrases. Singular terms are expressions that refer, with respect to contexts, to individuals. Most semantic theories of the simple demonstratives ‘this’ and ‘that’ treat them as singular terms. Speakers seem to use complex demonstratives to refer to individuals in much the way that they use simple demonstratives. That is some reason to think that complex demonstratives are singular terms. However, complex demonstratives syntactically resemble paradigmatic quantifier phrases, such as ‘some woman’ and ‘every man’. That is some reason to think that complex demonstratives are quantifier phrases. But quantifier phrases are not singular terms; they do not refer, with respect to contexts, to individuals. Their references, or extensions, with respect to contexts, are usually taken to be sets of sets.
