On the basis of a cross-linguistic study of over 250 languages, this book brings to light several fascinating characteristics of pronouns. It argues that these words do not form a single category, but rather two different categories called 'personal pronouns' and 'proforms'. It points out several differences between the two, such as the occurrence of a dual structure among proforms but not among personal pronouns. These differences are shown to derive from the
distinct functions that the two categories have to perform in language. The book also shows that the so-called interrogative pronouns of familiar languages do not actually have
interrogation as their meaning. One can only assign the meaning of indefiniteness to them. Further, the notion of indefiniteness that can be associated with these and other pronouns is quite different from the one that can be associated with noun phrases. Other interesting aspects of this book include the postulation of certain typological distinctions like 'two-person' and 'three-person' languages and 'free-pronoun' and 'bound-pronoun' languages.
