There are 27 pronouns, grouped in clitic and tonic pronouns. Personal pronouns are separated into three groups: subject, object (which take the place of both direct and indirect objects), and reflexive. Second person subject pronouns have both a polite and a familiar form. These two different types of address are very important in Italian social distinctions. All object pronouns have two forms: stressed and unstressed (clitics). Unstressed object pronouns are much more frequently used, and come before the verb ("Lo vedo". 'I see him.'). Stressed object pronouns come after the verb, and are used when emphasis is required, for contrast, or to avoid ambiguity ("Vedo lui, ma non lei". 'I see him, but not her'). Aside from personal pronouns, Italian also has demonstrative, interrogative, possessive, and relative pronouns. There are two types of demonstrative pronouns: relatively near (this) and relatively far (that). Demonstratives in Italian are repeated before each noun, unlike in English.
