Finally, languages vary along a typological dimension related to the things they tend to omit. Some languages, like English, require that we use an explicit pronoun when talking about a referent that is given in the discourse. In other languages, however, we can sometimes omit pronouns altogether, as the following example from Spanish shows 1 : (10.6) [El jefe] i dio con un libro. / 0 i Mostró a un descifrador ambulante. [The boss] came upon a book. [He] showed it to a wandering decoder.
